Please don't call a statement laughable when your own contributions are gameFAQs-level drivel about "VaLvE mAkE nO GaMes!!!" and continued bullshit about "proudly advertising" piracy, which I already addressed. Steam doesn't suffer in any significant way from piracy because they literally solved the service problem in the PC space (i.e. they made it easy and convenient to be a legitimate customer instead of a pirate, and invested early in stuff like regional pricing for digital goods, which addressed where high volume piracy is historically rampant: developing countries which have often been left to grey/black market activity without official distributors).
There's no demand for emulation of 99.9% of PS and XB games because those games literally run natively on PC and can be bought there. It's very obvious why Nintendo sees unique levels of demand for emulation: there is literally no legitimate way to access their 1st party software without also buying the hardware. This is the exact same reason PS4 emulation is suddenly progressing rapidly - there is high demand and interest driven almost entirely by 1 game that Sony have neither made more widely available nor even patched to make use of newer PS hardware. It's not some insane conspiracy of thought where someone buys their first GPU and immediately demands free Nintendo games and a copy of Bloodborne.
You are completely mistaken in the assumption that "nobody would buy Nintendo games on PC". By this logic nobody would ever have bought a thing on Steam, given how trivial piracy was on PC at the time. 99% of users do not want to jump through the hoops or deal with the significant downsides of piracy and will simply buy for the combination of convenience and value-adds (multiplayer and online modes/services, for example). This extends to all media - 99% of people will just pay the Netflix/Disney+ sub rather than fuck around with torrents and streaming sites. Nintendo want to keep a tightly integrated hardware/software ecosystem and are free to do so, but that has the completely expected trade-off that you aren't going to meet 100% of customer demand when you are adding additional cost to the customer to enter that ecosystem. Nintendo's job is to balance that trade-off to reach the maximum number of customers (that's where mass-market pricing and highly attractive software helps achieve that, and has achieved that).
Is SMB on phones or PC, where the piracy is occurring? No. Does anyone's previous purchases of SMB transfer to modern hardware? No. So it's absolutely a service problem, because there is clearly some level of demand but no legal supply until you go out and buy a Switch (this obviously works, because Nintendo have sold tens of millions of them). Likewise Gamecube/Dreamcast/Saturn games - literally the only legal way to play the vast majority of these titles is by fucking around with 2nd hand markets for ancient hardware and software, which 99% of people will not engage in. Again, near-zero legal supply until legitimate retro collections appear (which is thankfully now happening for these generations of hardware): a service problem. As long as Nintendo operates their business model (which I think is the right way for them to operate) they will always generate some amount of demand on other hardware that can demonstrably play the games - in the case of phones, it's computing hardware that's completely ubiquitous even in developing countries. It's up to Nintendo to make the case to the public to spend money on another device for the sake of videogames.
But piracy of Switch games have only become ever more mainstream, we have at least 1 million people confirmed to have been downloading ROMs of TOTK and playing it on PC, that would be a pretty big chunk of the potential PC audience of those games if Nintendo ever ported them over. God of War sold like 3 million on PC? So for Nintendo games, a large percentage of potential customers would already be lost from the current piracy figures alone. Which makes potential PC ports return much lower revenue then they otherwise would have done.
So yes, piracy of Nintendo games only makes PC less possible than if Nintendo could release their games on PC and there would be no alternative, cheaper ways to get those games on PC.
Sony and Microsoft also started their PC push after emulation of their hardware and software were no longer on a large scale, while Nintendo is still suffering from 90s style mass piracy even today, which puts them in a fully unique position in the current gaming market. We also know that the PC market is growing, the more people that own a gaming PC and/ or a Steam deck the more potential pirates of Nintendo products will exist. So if over a 1 million people today are pirating the biggest Nintendo games, that would easily swell in a few years.
Valve has been a thorn in Nintendo's side, given that they have fully worked to benefit from widespread Switch piracy for their own hardware products as well. No one that is active online can have avoided seeing that Switch emulation has been pushed as a big selling point for the steam deck, in that you can play both PC and Switch games, on better handheld hardware than the Switch itself, and those Nintendo products are free for Steam deck users as well.
But everything will depend on Nvidia and Nintendo themselves, they must reach the same standard of security as their competitors have reached, if it takes many years to breach their hardware then the piracy problem will automatically be less of a problem, because if the Switch 2 is safe from piracy for most of its active existance then nothing like what happened during the Switch era would be possible to repeat itself during the Switch 2 era. But if they fail once again, going the legal direction makes full sense, even if online rage against them will be massive. Because with new hardware, comes even higher budgets for Nintendo games, and with bigger budgets comes even less a case to be lenient in the case their products are made available to millions of people for free.
But i think that is what a lot of the debate is about, there are some gamers who think Nintendo is some sort of massive, untouchable company that cannot be hurt by piracy, but we can only go back to how dismal their sales was during the Wii U to see how only a new failed generation for Nintendo can hurt them massively as a company, and with piracy problems to bout could lead to mass layoffs happening and fewer Nintendo games, which is why some who enjoy Nintendo products fear piracy problems for that reason.
