For instance, if I want to drink radiation laced water, Libertarians would think I have the right. They'd also say I should have to pay for my own medical treatment resulting from that. Reasonable enough.
However, if I drank radiation laced water because a chemical company was disposing of their waste in my backyard and I didn't know, Libertarians would tell you it's your fault for not having the proper testing equipment or paying a company to run these tests for you.
The same thing shakes out for food. For employment. For air travel. For basically everything you do you're assumed to have done enough research to know the risks you're exposed to. Libertarianism also makes the enormous assumption that a safe option will always be available.
Since there's zero protection from monopolies in a pure Libertarian society, they will naturally occur, and the results will be overwhelmingly negative for all but a handful of people, the proverbial 1% if that.
Libertarianism also as much as endorses discrimination as it sees it as your absolute right to decide who you provide goods and services to. Idealists would have you believe that non-discriminatory companies will always out-perform their discriminatory counterparts, but history has proven the opposite. If people are racist, they will certainly pay a small premium for service that reflects their views.
It's this every-man-for-himself approach to living that quickly degenerates into pure Darwinism where the one with the most money, who can easily afford to build a protective bubble around themselves, thrives and the others live miserable, dangerous lives.
Basically a pure Libertarian approach has too many dangerous failure states for it to be taken seriously. There are arguments that can be made for a more or less libertarian approach to problems in society, but to go 100%, full-on is to miss the point.
