Yeah, but see, my mate Joe, he just doesn't run the sign up page or authentication or the matchmaking or the seasonal DLC or the voice chat or the community forums.
He just enters some stuff by hand into the Oracle DB and off we go.
I'm serious. Big corporations tend to overcomplicate this stuff all the time. Especially because they tend to run several components as one. But when you break it down each one is not that complicated. I've done that. As my job. Saying it's not feasible is a massive strawman.
Because as always, if they can do it so can we. This will never change.
