It may also end up using their account for other tasks like backups, and what if I forget that super strong password I made 5+years ago and Sony decides I can’t get that account back.

I had a PS3 with accounts I wanted to come back to, and without Sony’s approval they can just lock you out, even if you have the old email it was linked to, along with some transaction information. Locked out of games I paid for. We’ve seen plenty of hostility towards this practice from publishers, but Sony is big enough they can skate by.
