The problem is that libertarians will use the ideal about free markets to oppose any sort of sane regulation or discussion about the limits of the market. I would say markets in the US are rigged in many obvious ways, due to the outsized influence of business in American elections and the political system. So much of business regulations in the US is written by people from the very same business and people who oversee the markets are often from the same industry they are supposed to regulate and go to fat jobs in the industry after they have done the bidding of the industry in the public sector. Whether it is Tesla, broadband, telecoms or utilities you see the established players effectively block new entrants with all their political connections.

Just look at the ridiculous situation with patents, trademarks and copyrights. All of them have long outgrown their original intention and has been so amplified and extended that they can be used to very effectively kill all smaller competition and milk consumers dry.

The argument that government is horrible has been used effectively again and again to make government horrible. Is has been stripped of cash to work effectively and become completely dependent on largess from the private enterprise to function. That attracts the most rotten people as politicians, thus ensuring that government never looks good. The last thing these people want is a well functioning government.
