Couldn’t you apply that same thinking to all compute? Servers will always have more, timesharing means lower cost, people will probably only ever own dumb terminals?
Never could figure out what the heck the value proposition was supposed to be though. Pay full price for a game that you can't even pretend you own? I don't think so. And the game conservation implications were also dire, so I'm not sad it went away in the end.
But on technical merits? It worked great.
