food production and distribution is also heavily regulated. the USDA inspects farms for safety and sanitation. the FDA inspects food processors for safety and sanitation and inspects food products for safety and purity (whether or not the item in the package is what it claims to be).

I don't know precisely how this compares with the degree of regulation and government intervention in the healthcare sector, but I wish you would try to make a more concrete argument with some examples or citations. as is it really seems as if you're arguing purely from ideology.
