This idea that you should have to log into an online account, in order to use a device that is otherwise entirely offline, is the root of all evil in consumer electronics today. Not just game software and game consoles, but PCs, TVs, smartphones, home automation... Everything requires a totally unnecessary tether to the manufacturer, and only allows you to use it if the manufacturer is 1. still listening to the connection, and 2. is satisfied that you tethered properly.
I shouldn't need an online account to use 99% of the things that I have that currently require an account.
