You didn't respond to what I actually said. I wasn't arguing whether taxes are good or bad, I was asking what would happen if they were optional, and whether real solidarity only exists without coercion. Infrastructure and security don't require a state, they can come from communities, cooperatives, or markets, and 'move if you're determined' is survivor's bias: most people can't. The difference between a taxpayer and a subject is consent, and consent under threat isn't consent
