Banks aren't punished for counterfeiting

If part of the economy should have deposit insurance (the banks) then everyone should be protected from failure by the state... there is nothing intrinsically special about the banks. To take deposits confers no special authority or importance. The free market is able to provide (and price) security. The problems of deposit insurance (inflation) are not remedied by restricting its scope to only banks. (Giving it to everyone would not be much worse.) If banks should have it then it should be available for everyone.
