If steam disappeared you are no better off than if xbox did.
Steam DRM can be trivially removed. 3rd party DRM is a problem, but thankfully not all games use it and many games have had their DRM removed as well (either by the publisher or through crackers).

You still couldn’t redownload games that you bought, that’s the point.
