This will be a big thing. We could give people an allowance of a certain amount of land that is tax-free (as we have in the UK for income).

In the longer term, government could also be self-sufficient. This might be unstable though, it might be better for there to be a contribution of materials/energy/information to the the government from self-sufficient communities. The government would still provide the value of protection/arbitration to the self-sufficient communities.
