And by libertarian I mean the government will ONLY be involved in protecting its citizens from direct harm from other humans (so only military and police).
Scrap all the welfare, regional taxes, health taxes, everything. Every citizen should pay an equal tax, no matter how much they earn to support a very tiny government.
That way, it's impossible for unfairness to exist. You create your own company and can decide to hire whoever you want. You can be racist, sexist, etc. So long as you don't physically harm anyone.
That way, if you don't like the views of someone, don't buy from them. If they don't hire you because you are a woman, open your own company and you'll be able to beat the competition if you're truly better than the men you think the "discriminating" company hires.
The only reason people think inequality exists is because the governmnet meddles in the affairs of people too much.
Withotu the government people can choose to spend their money however they please. You want to support women? give them your own money! Etc.
