You don't have to! Oh yes I do, see the above post explanation of the "FORCE!"
You can forego Medicare if you want.
You'll just have a real hard time finding an insurer who is willing to take a risk on an 83 year old asshole.
Absolutely NOBODY, except the very wealthy can "forgo" Medicare after age 65. The feds have that scam in the bag. Buying private insurance after 65 would bankrupt the average person, thanks to the Medicare & Medicaid programs themselves that inflated the hell out of private insurance rates.
So you're a socialist in practice only.
Everybody that lives under a government is forced to live under some degree of socialism. Government is socialism by definition. we can always argue about how much socialist government is worthy of being instituted, but Our Constitution lays it all out for us in Articles One, Two and Three and the amendments. Regretfully the swamp rats ignore our Constitution.
