The whole "PC is an open plataform, has different stores" argument to defend digital distribution on PC while trashing it on console is one of the biggest fallacies I've ever read.
The PC market is practically a Steam monopoly. The "other" stores are virtually no competition to Steam. In some cases, they actually worsen the experience because they force you to use a different launcher that can be super shitty. Alan Wake 2 for example can only be acquired through the Epic Store, and is reliant to its servers to be up to even play. Recently they went down for days and people weren't even able to play the game they purchased.
Steam has the exact same distribution EULA terms as the console makers. It's exactly the same. "Oh no but they actually went out and said that if someday they go down they promise to make all the games DRM free to people", really? Did they wrote that on their terms? Until then it's pure PR bullshit.
I'll argue that if you somehow make physical games for PC today with console standards (playable on disc, transferable, etc.), the model would completely fail. People will keep purchasing their games on Steam. Even if that means they don't get to "own" their games. And that's because Steam was able to be reliable and stable in maintaining their digital library.
If Valve, which is a microbe as a company when compared to Sony, MS and Nintendo, was able to pull off a steady digital distribution system, I have no doubts these last three companies will be able to manage the same.
My point is, sooner or later consoles are going to be all digital, and things are gonna be FINE. It's not going to be this dystopian, post-apocalyptic, lovecraftian, orwellian, nuclear-wintered future you imagine for your games. RELAX.
