How do you know that Steam will be around in 20 years?
Use GOG instead, since the DRM-free game installers will outlive Steam :)
How do you know Windows will keep compatibility in 20 years? Valve money partially goes into Proton/WINE development and an evolution of that will absolutely be around in 20 years, just WINE was around 20 years ago already. CD Project doesn’t put any GOG/Cyberpunk money into breaking the Windows monopoly. (Also plenty of titles on Steam come without DRM because DRM is optional.)

My GOG games run great on wine, it just takes a bit more work to install them. Wine has better support for early windows games than windows does now.
I didn’t mention Windows anywhere in my comment? GOG has Linux versions of games too, for games with Linux ports.
That’s true - for the DRM-free Steam games, you can just keep a separate backup copy of the game files. They usually run fine without Steam installed.
