Nobody owns their land in states that have property taxes. It is just like renting your property from the government. If anyone gets ill and can't afford the property taxes the government will kick them out of their homes and take them. Property taxes need to be eliminated in this country so that people can truly own their land.
Sales taxes would be the best way for local governments to get money. As the population increases and spends more money, more money would go to government. People who grow their own food would not need to pay taxes on the food they kept. Groups of poor people could band together to own some land and share the food production of that land without the government demanding taxes for that land.
This man is a great example of what is possible in America. If I were a vegetarian I could go for such a lifestyle, but maintaining livestock takes up much more space. I know that many suburban areas ban any form of livestock.
