You’re confusing the Libertarian party and ideology with the term Tea Party Republicans use to justify their version of crony capitalism that they call free market. Big government provides a lot of regulation that is only needed due to the inability for competition in a lot of markets. The lack of competition is due to barrier to entry laws written by the propped up corporation. Remove the subsidies and allow competition and the need for regulation will remove itself. It’s false to believe Libertarians want to take over and remove all government protections right away. That is an end goal but it is a goal that has to be achieved via a progression away from governmental reliance.
