“Overhead to starting businesses” is not the only metric to take into account though. I’m not going to defend any given regulation necessarily, but your ad reductum fallacy is to think that’s the ONLY factor that must be considered. Consumer protection, environmental protection, worker protection, etc, etc, all can and should be taken into account in the calculus for regulations. Besides, many problems with starting a business come from monopolistic practices, not regulation, and reducing regulations will just make it cheaper for the mega corporation to keep their monopoly, at the cost of all these other factors.

So anyone who just goes “grr, regulation bad”, I can’t take seriously. If you have specific examples of regulations that are objectively bad, and should be removed, that’s fine, but the examples you cited protect something else, and ignoring that is intellectually dishonest at best, and blatantly partisan at worst.
