How can one use barter trade if we have to get fiat to pay property taxes? If I hide away in some far off land and farm on other people's property and hope that they don't notice, and then barter trade, I can see how one can use land to farm and trade for essentials, but if I have to pay property taxes and not make any fiat in barter trading then how can barter trading work if the government will kick us off our land and possibly arrest us if we come back to the land and farm against the governments orders?
