Well said! Reminds me of an argument I saw on @larkenrose's Facebook wall just this morning. Technically, you are correct in that the "human farmers" of government do lay claim to everything within their geographic borders and we all pay rent to them as debt slaves known as "citizens" but the other side of the coin is also true:
Authority is an illusion.
Their claims of ownership are invalid and unjust. I pay because of the threat of violence against me, but I still advocate for a future which has no imaginary borders and individuals can own and improve their own property directly without a nanny state getting involved. The more people who free themselves from mortgage debt, the more people will ask, "What am I getting for this tax payment I have to make? More drone wars? This is ridiculous."
I'm all for voluntary payments to improve my community and if I am going to have theft taking place against me, a land tax in Georgian model doesn't seem all that terrible... but it's still theft. We'll get there some day, even if it's my children's children's children.
