No, I'd say that's why you want DRM-free games. Plenty of games don't even get physical releases because the economics don't make sense, and then they get crucial patches that fix game-breaking bugs. Your console will break over a long enough timeline, and eventually the parts to fix it won't be produced anymore; I doubt your Switch will still play Breath of the Wild 40 years from now. Basically the only way to preserve modern games that makes sense to me is to make them run on PC, DRM-free.

The playability of old games and not requiring paying again for a remaster/ release can only hurt their bottom line.

Nah, because making that remaster or re-release costs them money and is more of a gamble than just putting out the old version for cheaper. Most of GOG's business is built around this, and then you see things like Sega putting out a huge collection of their ROMs entirely DRM-free with ROM hacks built into the Steam workshop.
