Libertarianism is anarchy but with rules set forth by right-wing morons.
Most libertarians would consider themselves "Fiscally irresponsible and socially removed".
Anarchists on the other hand would say something like "no gods no masters". For libertarians to match something like that, they would try but then break down and vote for Ron Paul.
Anarchists accept the world around them.
Libertarians try to return to the gold standard, despite gold not carrying much value any more. Libertarianism wants to make america great again, since Libertarianism at its heart is a right wing religion.
People who claim to be libertarians are at a special place in life where they beleive the world can be changed for the better by giving everything to the ultra wealthy and leaving us to fend for scraps. Libertarianism isn't a legit political science.
This is just a TL;DR: for a better understanding of life as a libertarian, dig a hole and stick your head in it. After all, the only way to understand someone is to think like someone.
Libertarians, upon breaking their bones and being unable to afford treatment respond with "that's ok, it's the free market!" When the last doctor in their area refuses to treat them because they didn't make enough money. "Social programs are for losers!" The doctor nods and turns the libertarian out on the cold winter street. "The free market provides!" Mutters the libertarian.
