I would be with libertarians if they didn't go to the extreme of wanting no regulations. There should be regulations for the environment and for creating fair market conditions. Healthbcare should be regulated in some way to ensure accessibility.
Whatever I hear from libertarians will lead to people with money accumulating all power in the same way we see now.
Libertarians oppose crony capitalism and the use of state power for special interests in general.
The libertarian theory on regulation is that the market punishes bad behavior way more effectively than the government, which can always be swayed by political forces. During the Industrial Revolution, for instance, judges sided with corporations in pollution cases, thinking, "We can't hinder industrial progress for the sake of a few people's lungs." So the government granted monopoly pollution privileges to industry. Under a free market property rights scenario, any damage done to another person via pollution would be grounds for a suit against the polluter, no special government protection.

In the libertarian world you just sue when you are being wronged and justice will be done. In reality if you sue a big company you have to go against an army of lawyers, expert witnesses they can buy and media campaigns. You simply can't win that unless you have a lot of money. We still would have lead paint if the EPA hadn't banned it. How can a single family prove to a court that whatever problems their children have is caused by lead paint? Fund a clinical study for a few million dollars?
