My "liberties" do not entitle me to be a rocket scientist just because I want to.  That's in fact antithetical to a libertarian viewpoint -- either you're capable of becoming a rocket scientist and you work to become one -- or you don't because you either didn't work to become one or you weren't capable of becoming one.

You aren't guaranteed the right to become a defensive tackle -- but you are free to try to become one.

Receiving a professional license is choice - any liberties -- any invasion into my personal life necessary to secure and maintain those licenses, are decision I and I alone make.  I'm aware of the choice - and I choose to pursue that license or not pursue it.

Libel laws don't take away my liberty -- they protect yours.

I'm not sure exactly where you're getting your views on liberties from -- but they have nothing to do with mine, nor, I suspect -- anyone that values their freedoms to the degree that I do.

I'm not an anarchist - I accept the payment of taxes.  I accept social programs for the common good.  I happily and always vote "yes" for school funding initiatives... public works projects... I even believe in universal access to healthcare.

What I have a problem with are situations where the government - any government -- chooses to interfere with my private life.  If I -- an adult America - decide for whatever reason, that I do not wish to have healthcare... say I believe in faith healing... or new age/alternative medical care... or just plain don't like doctors -- then I, an adult American -- should have the right to refuse a health care plan and the government should not penalize me for exercising it.
