Since you’re talking about ownership, remember that most “purchases” via Steam have DRM in them. If you really want to own your library then purchase from GoG and have your games downloaded to an external harddrive. You can easily access your GoG library via Heroic on Linux.
That’s up to the game developers, not Steam. Many games on Steam don’t have any DRM, you can copy the files anywhere you want and just start the exe without Steam even being installed.
