seem to imply we could never assign a monetary value to independence. How much of my real income to I have to give up to get the Ethnostate? 25%? 50%? Either way that's reasonable (for me) if it comes to that

Less money is one thing, but it would be like being an average black person living in South Africa. Charge your phone from the communal car battery kind of situation. You wouldn't have access to your same standard of living.

I don't think an economic embargo is that likely

It would cost them nothing to cut you off for no other reason than to punish what they perceive as insolence.

The military (for now) is also largely made up of conservative whites.

The rank and file is mostly minorities. It's a path to citizenship.
