Secession is an empty topic. “Buy-out” is a possibility, though. The commies LOVE money.
I think secession is on the far end of a spectrum. Some form of political divorce is probably inevitable, but what form that takes is an open question. And there are other models of alliance within our own country even today such as a commomweath or territorial status.
For example did you know that the residents of the territory of Guam do not pay Federal income taxes? The government of Guam collects income taxes in essentially the same amount but retains that revenue.
