At this day and age, the concept of region locking is just stupid. Steam has no hard rule to lock your account to specific region, Xbox Live allows you to change your region just like that as well as id. But for some reason, psn is still locked into the region you use. This becomes a pain if people need to constantly travel. Creating a new account would mean new friends, lost save games, trophies, game purchases etc.
I know how multiple accounts work as I have 3 of them from 3 different regions, I use US account as my primary account. The point I am trying to make is, it shouldn't be this way. I mean I want to keep one account with all my purchases, I don't want to keep seperate accounts.
Either let us change account region for those of us who travel regularly, or...even better, like Steam and Xbox, throw away this region lock, which is just stupid during this age.
