Fair enough.
Staten Island merely wants to secede from New York City, though, not the state. AFAIC, Article IV Section 3 of the US Constitution doesn’t apply here.
I surrender. You are right.
I have read this inadequate book American Secession by F.H. Buckley. It mainly concludes the problems of who pays for the US defense bills and who gets the tax money and so on make it a fantasy. He did correctly predict investing money in UHaul and others was smart (and migration to other states to get away from people we hate was one of his themes.)
I saw a reference to this Buckley (not a William F. Buckley relative) being an early Trump supporter but I heard an interview where he laughed at the chances of Trump winning in 2024——something I don’t find amusing in the slightest.
