I think the problem has other sides to it, not that they aren't able to be overcome but, for large communities with very diverse desires, there is likely going to always be requirements for a tax of some sort to cover the communal needs and not everyone is always going to agree to the expenditure.
Governments and their failings are somewhat of a symptom of society in my view.
What about fair responsibility to the community done voluntarily, not blind coercive extortion t be forced into paying for things?

My comment so you get an idea what it's about:
Of course, but some things require more than people are willing to give now. I am not saying it won't work later though but there has to be a fundamental shift in the majority of people doesn't there? It can't just be a few who volunteer while the many or high value extract or support only what they want. That is the issue here with Self-governance, it is more self, than governance.
