Except for drug control, gun control, sex control, God control, and about 15 other controls...
I wouldn't call anyone who supports gun control "conservative." I don't think that anyone who advocates a state-established religion is conservative, either.
I don't know what you mean by "sex control." I don't want the gov't teaching my kids to accept gaydom, but I don't think any libertarian would want that either. I also don't want hard core porn broadcast over the airwaves. But if libertarians had their way, we wouldn't have open airwaves anyway, with everyone and their mother broadcasting on whatever wavelength they want.
As for "drug control," drug trafficking is clearly a form of foreign and/or interstate commerce, and so the Constitution allows the feds to get involved. That's one instance where libertarian ideology is at odds with a perfectly constitutional form of government--although in fairness, the Constitution certainly doesn't require a federal drug trafficking policy.
