I think you're underestimating the network effects of widespread, private gun ownership. It's true that private gun owners will rarely coalesce into a potent political organization (NRA notwithstanding), but those types of organizations often form in reaction to external pressures. In other words, the more oppressive the government becomes, the more likely such organizations would be formed.

Additionally, even without formal organization, they do serve as deterrents against crime. And then, of course, there are also individual benefits, but that's yet another matter.
