TPB is not about USA-made content, it's about any content. If a service wants to replace piracy, it would need to provide similar content, which Hulu/Netflix/etc don't.
Hulu/Netflix/etc are not about USA-made content either. They have content from other countries, wherever rights could be obtained. Regional restriction is due to content rights, not due to content itself.
TPB provides you (illegally) any content anywhere.
Hulu/Netflix provide you (legally) certain content (that they have right to) in USA (where they have content rights) and a few other countries. This is a large restriction.
Now biting the troll: other places do make good shows/films/games.
