I am sure it's going to be an issue at some point in the future, it already is an issue when it comes to sharing games or keeping older versions around, but what's the alternative? The alternative isn't no DRM, it's whatever DRM Apple, Google, Microsoft, Epic, EA and friends come up with, and of all of those, I take Steam any day.
Even GOG kind of loses to Steam here, as while GOG gave us DRM-free downloads, Steam gave us Linux support and Windows-emulation and I'd rather have Steam DRM on Linux than being stuck on Windows with DRM-free GOG games. And unless I am missing something, GOG's DRM-free games didn't lead to a used digital games market either, they explicitly forbid selling or sharing in their user agreement[1]:
>> 3.3 Your GOG account and GOG content [games] are personal to you and cannot be shared with, sold, gifted or transferred to anyone else.
Digital goods ownership is just not a thing that exists at the moment. There was an attempt based on blockchain with Robot Cache[1], but that just shutdown.
