I agree with all of those points. The market unfortunately doesn't. Physical sales constitute only a quarter on the PlayStation platform (even less according to Sony). Most if not all of the top 10 games by player count are online only anyway.
If Sony does go all digital with the PS6 they'll only lose a small fraction of loyal gamers and they just don't give a fuck.
Piracy on the PlayStation? Also not gonna happen. At least not for online games and that's where the money is.
