This may be technically true, but such action by Alabama would have to pass muster with the Supreme Court on whatever basis they do claim, even if it’s a “secret” basis or no basis at all; and beyond that, their decision would also have to pass muster with the court of public opinion eventually, including their voters, other governments, corproations, investors, tourists, etc. That last one might strike some as who-cares-big-whoop, but if everyone up and down the line thinks of Alabama as a clown state for doing things that are so untethered from reason, then good luck being taken seriously at whatever point they’d need to. That would not matter only if they can be a self-sufficient entity that doesn’t need anyone or any other entity for anything else ever again.
