We can't have a gift economy, where people give things away for free, because the government makes one need to make money via the institution of property taxes and land ownership of everywhere, rather than people simply being able to move on land and own what they create or purchase, perhaps with an area of space in which they consistantly use being reserved. Property tax and lack of everyone having access to land also stops one from being able to make wealth without either having wealth, a job, or government assistance, a main cause for needing welfare at all. People who can't get a job should be able to survive without resorting to government welfare by making their own wealth directly, but sadly, the government doesn't allow that. Yet again, a solution from the Civilisation only fixes what was caused by it in the first place.
