It depends on the game. Like if it’s an online only game, then of course that makes sense. But a single player game, or even a game with a single player mode requiring always online is and will always be dumb.
Diablo 4 not being designed for offline solo play as well (like D2 and I think even D3 was) is annoying though.
I think we are a long, long ways off before we could even get to the ‘could’ phase of the discussion, let alone asking if we should.
