An account that you can only have in 73 countries, while the game was originally sold in ~190. The PSN ToS is pretty awful, but what got a lot of attention was Sony just retroactively making the game unplayable for over half the globe. Yes, you can lie and give them a fake address, but in the ToS they can demand ID to prove your identity and location.
When I moved from one country to another, PSN wouldn't allow me to pay for things with the card issued by my new bank - I ended up having to open a new Sony account
I'm not sure if things are the same now - that happened in the era of transition from PS3 to 4
