True, but what solves the forced rider problem and why presume that it is more benign a problem than free riding? One man's public good is another man's public bad.

There's no a priori answer: democracy is how we decide. But one way to check how we're doing is by comparison with other countries: http://en.wikipedia.org/wiki/List_of_countries_by_tax_revenu...

The US's tax burden is already the lowest of the OECD countries bar Chile and Mexico. It's 30% lower than Great Britain, and half that of Denmark. And what that hides is we spend an extraordinarily large portion of that on "defense", so in terms of money spent on citizens, we're necessarily lower.

But if that's still too much governmental interference, then tax haters are able to select from a wide variety of third-world countries. I might suggest Somalia, where effective tax burden is zero. There being no effective government at all, of course.
