Sorry but in the case of Japan, it's definitely not logical. At best, they have an argument against over-tourism. But the Sanseito party acts like foreigners moving to Japan are creating a spike in crime. They literally have young women weeping through a megaphone on the street, crying that foreigners are rapists. But that's simply not backed up by statistics. Crime per capita has not increased, and the demographic committing the most serious crimes in Japan is predominantly native Japanese.
I mean, it would be an interesting experiment I guess. I suspect it would effectively segregate the states by ideology and race. I assume most non-old-white-christians would prefer to live in blue states.
But one glaring question is how would we divide up existing federal resources? Like the military, bank, etc.
Pff OK if that's the argument you want to go with, I don't think we need to continue.
