While I myself called myself a libertarian for some time and find their general view of the world much less repulsive than your typical American, there is one major flaw in this ideology. It’s ultimately what lead me to call myself an anarchist.
Simply this: If governments enforcing political ideas via force is not palatable in some instances (such as what we put in our bodies or do in our own bedroom) why are they acceptable in others?
If you are against force and coercion the answer is simple. Government is not morally excusable and has no right to enforce anyone’s ideas or wants, let alone even exist.
To limit government to a small, but somehow acceptable amount of uses, leaves an opening for what only promises to be a slowly expanding number of uses until your “limited government” isn’t so limited anymore. Bring back Thomas Jefferson and his buds and ask them if they agree now.
