Your definition of "duress" is so extreme as to be absurd. Just about all important decisions would be thought of as being made "under duress" which means you can justify unlimited intervention into any segment of the economy because someone will always either need the good or the job. In the US, only about 5% of healthcare expenditures are for emergency care. That means there is huge opportunity for people to shop around. The problem in the US is that there's no actual healthcare market, so shopping is impossible. No prices are displayed so customers can't make informed decisions, most areas are operating under healthcare monopolies, and most areas enforce a perverse set of laws that make it difficult for competition to enter the market.
