The fact that you equate economic stabilizers with money creation strongly suggests that you are not interested in genuine discussion. If you seriously believe that equating those two things is in any way reasonable, then believe me, you're just confused - and if you
are genuinely interested in learning more, holler (but it might take a while for me to respond in detail because I'm traveling).
One important point though is that welfare provided by local governments cannot be sufficient. Local governments are entirely dependent on tax revenue and the goodwill of creditors. If a local government is hit badly enough by an economic crisis, they will be unable to continue providing this welfare.
This is especially true if other local governments in the same currency zone are less badly hit by the crisis. In this case, creditors will "flee" towards those other local governments, which creates a vicious cycle.
The previous paragraph is exactly what happened in the Eurozone, except that national governments played the role of local governments.
