The idea is great in theory ... practically, it's complete trash.
In my country, you can buy Youtube Premium subscription with 1$/month using student mail address. The same thing apply to the most services.
Is not a good idea to buy subscription from those countries because you will be restricted to that region content It's awful to receive content in turkish when you only speak english. Also, i've seen that the biggest majority of website will ban or restrict you sooner or later if your ip doesn't match your checkout adress. I knew some guys who kept selling Youtube account and they got flooded with unhappy customers who lost access to the account.
