Nice straw man. The originating subject was on taxes (since it takes more than a city to provide all of those services), not only SF taxes :-)
San Francisco residents live in the United States of America. The United States of America imposes federal taxes. Federal taxes have been used to fund wars and bailouts of various failed businesses.
Of course, no real city has the authority to have a military. The city does have a police force, which often acts in ways that do not better the lives of SF residents (parking tickets for example).
It's not like "public transportation, fire safety, paved roads, bridges, public schools, police officers, health inspectors, safety inspectors, public parks, libraries, clean air, (relatively) fair corporations, airports, hospitals, court systems, electricity, vehicle regulation, elections, veteran associations, child support, public television..." is entirely in the domain of the city government.
I just have a adverse reaction to arguments that claim I should appreciate a service provider that charges too much. Sorry, don't like getting ripped off.
