You don't need DRM when your customers don't actually get a copy of the game. Like Microsoft's new Game Pass Ultimate feature where you can subscribe and play XBox console games from Windows, streamed from the Cloud. This is what they are up to. You no longer need to own a console or purchase the games. I imagine they will be pushing a future where games are written primarily for these virtual consoles, and using the correct APIs your games will automatically look better as the virtual consoles become more powerful. As for preserving games, this is purely a call for publishers to permanently license their games for this service (ie. if you license music, make sure the licenses don't expire and are compatible with streaming game distribution).
