What natural right do these regulatory agencies (or group of thugs known as government) have to regulate free people who choose to associate freely? What they are doing is deeply immoral.
So, there is really no objective justification for the existence of US government, because its supposed purpose it to protect 'basic rights', such as life, liberty and pursuit of haaapineeess(i.e. ensure that subset of homo sapiens species can release endorphins, dopamine, anandamide...). Since rights don't exist, there is nothing to protect. It's kinda like paying security staff to protect non-existing house. BTW, contingent rights flow from natural rights and if those are illusory, then all rights and laws are not justifiable.
(hint: the answer is none, because there is no such thing as a "natural right")
