Perhaps. Good luck skipping out on paying your taxes or filling out the census

If you can only make such absurd examples then you have failed. Paying taxes are not a contract between me and the government. They are a forced fee extracted of me. Everyone should be worried about the government threatening to issue supply chain risks if they don't like you rejecting a contract with them.

Paying taxes is a tad different than being a DoD contractor.

both fall under the umbrella of civic duties

Its not a fucking civic duty for my company to be forced into entering contracts with the government. Its my civic right to tell the government to pound sand without fearing forceful retaliation.
