The libertarian philosophical response would be that people only have the two basic rights to life and property. And one person cannot take away those rights from another. The government then exists solely to limit behavior strictly only in cases in which one of those two rights are being taken away by another individual.

The point of that argument is that no individual has the right to do with the government what he would not be right to do by himself. This means that since he can't individually limit the rights of another, he can't use the government to do it either.

This means that there are no concessions at all to personal freedom to live in a group. Not really anyway. I mean, yes, you can't take someone else's life (unless they attempt to take yours.) But that's hardly a restriction necessary only in large groups of people. It's kind-of implied as soon as you have at least two people.
