That’s not how anything actually works in the real world though.
The arguments against libertarians are almost always some absolutist interpretation of some anarchist movie is world or worse Somalia which has tons of tribal systems, failed states (which includes a fair judicial system and enforcement of the law which markets absolutely depend on) and very little developed capitalist industries.
In reality most libertarians want a smaller government than is currently in place, they don’t want zero government. They most certainly don’t want an unstable state without centralize state run courts or law enforcement (outside of a very tiny extremist minority, a far smaller minority in the world than those who want actual vanguard communism again).
I’m a pragmatic libertarian leaning person which means that being realistic means compromise that some industry just simply makes more sense (as the amount of trouble it would cause to be market based via uncontrollable externalities). You could even factor in the amount of natural political meddling like we see in the US healthcare markets, which creates fake pseudo markets that provide few of the benefits of a real market where a single centralized public insurance option may actually be the least evil option, since the alternative has long ago become unrealistic. But that said I’d go as far as up to 50%+ up industry intervention and pro-social projects (ie helping the poor) are actually making things worse off overall had they not existed at all.
Thomas Sowell has written some great books documenting hundreds of cases of gov intervention coming with good intentions that have backfired (ie. rent control in Toronto and NYC in the 70s and 80s which dramatically reduced the supply of new low income development because no one wanted to build with rent control when they could build somewhere else).
I recommend “Wealth, Poverty, and Politics” by Sowell as a starter.
For other examples of failures of gov run central industry making them worse off than before I highly recommend reading the Venezuela economy Wikipedia about all the stuff they did after declaring capitalism is old and dead, creating mass starvation and unnecessary poverty in what could have been the most successful country in South America. Meanwhile countries like South Korea, Taiwan, Singapore, and Hong Kong adopted markets after having large state run industry and dramatically increased the wealth of their entire country in a short few decades.
I 100% agree that there are horribly misguided policies pushed by many progressives that do more harm than good. An overly aggressive minimum wage would be devastating to underskilled or undervalued workers. Rent control is a disaster. Markets are an amazing tool, and few things are more dangerous than a bleeding heart progressive that doesn't understand markets.
But I believe markets are just one tool that a wise society employs to create a prosperous world where everyone has the basic necessities and access to resources to allow them to flourish.
Honestly, it sounds like you and I aren't too far apart.
