That comes pretty close to my definition of libertarianism. I believe it is also not too far from "classical liberalism." I believe it is also not far off from what our founding fathers had in mind.
"Absolute and unrestricted liberty" is not what I think of as libertarianism, but was suggested by another poster. However alot of folks who call themselves "Libertarians," such as the ones at Lewrockwell.com, seem like damn fools.
