Yeah, the only caveat is that you don’t get an installer with steam, so if you copy the installed game onto a pc that doesn’t have all the correct dependencies installed (like the correct DirectX version for example), then the game won’t launch. But it’s not too complicated to install the dependencies manually
Same thing applies to Steam. You don’t need to use the Steam DRM if you don’t want to, it gets added by the developers/publishers. There are plenty of DRM-free games on Steam
Yes, because the only people buying Nintendo Switch games are the ones who don’t care about the price in the first place. If you want to save money on switch games you just pirate them
