So for actual freedom wouldn't it make sense to take care that everyone can have a life of a certain standard - get food, a place to live, healthcare, education for free (not something luxurious, just something)?
Wouldn't a minimal state be extremely bad for people that have "bad luck" (disabilities since birth)?
Some claim charity can take care of that. Personally I'm not entirely sure... Though just because you are disabled doesn't mean you can't contribute. Look at Steven Hawking.
That's why I call it luck. Stephen Hawking at least had the luck to be in the right social environment.
Wouldn't it cause companies to create/be dictatorships (look up on Foxconn, they have more employees than some states have citizens and completely control their lives)?
Wouldn't such a society destroy the free market, because of stuff like monopolies?
Not counting the government (har har), can you name a monopoly that exists now that can't be destroyed by a free market? We had a few companies grab power temporarily, but that never lasts... (Microsoft, Kodak, Ford, heck, even Foxconn will die as soon as Africa opens up, or 3D printing at home becomes more widespread)
Wouldn't we have all the benefits of a Libertarian society already if people would actually care about stuff like what products they buy and why would people care more in a libertarian society?
They wouldn't care any more or less than they do now. People still shop at Walmart, buy BP and Exxon gas, etc. I don't think this will change.
