Why are people so affraid of anarchy?

[Thumpalumpacus]

Because there would be no mechanism for redressing breach of contract except taking your business to another company which may well do the exact same thing. In the meantime, the patient's still dying.

An insurance company wants to kill its customers? What kind of twisted logic is that?

Insurance companies want to minimize outlays. They can and do drop customers whose claims get too expensive, and that happens even with regulations. It has happened within my own family, nearly killing my son's mother while she battled cancer.

I suggest you reread what I wrote and refrain from imputing views to me which I don't hold.

I also suggest that you read up on history. Anarchy doesn't fare well, and as I mentioned earlier, we have a modern example. I wonder why you didn't address that point?

Bottom line: anarchy relies upon the premise that people will do the right thing in the absence of legal authority. That is a very shaky premise which lacks any evidence on the scale required by your claim.
