Article I, Section 8, Clause 1: The Congress shall have power to lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for the common defense and general welfare of the United StatesNationalized healthcare which you’ve previously stated you're against, for example, would likely be payed for by a tax. If you remember, the Supreme Court ruled the penalties within the ACA amounted to a tax and were legal. Article I Section 8 also outlines Congress’s ability to regulate commerce, despite your claim that amicable interactions of private individuals “minding their own business” are outside its jurisdiction. You can be against all of these as policy, but that doesn’t mean they breach the social contract or are somehow immoral.
Your Rugged Constitution[1], while old, is interesting because it frames each Article in terms of both what you give and what you get from the social contract, the former part being lost on many people. For example, regarding the aforementioned clause, you give the federal government additional power in exchange for the ability “to take care of the needs of the country at home”, I.e., general welfare.
