> The fact is, a lot Puerto Ricans like the current setup. The are natural born citizens who have full freedom of movement within the U.S. while Puerto Rico has fewer federal restrictions and obligations compared to a U.S. state.

I think you have it reversed: Puerto Rico suffers from all of the federal obligations and has no states' rights to make up for it. No representative, no voting senator (and therefore no 'pork'). The burden of the federal restrictions were bared in the aftermath of the hurricane: the Jones Act meant relief could only be transported by American ships even as other countries stood ready to help.
