It's always amazing and disappointing to see how many people actually believe that prices can be lowered by legislative fiat, or that "price gouging" is an actual thing that happens. I guess they would prefer to have shortages instead of paying market rates, and then complain about "greedy big business" or (my favorite) "late stage capitalism".
People who buy health care in the US already get de facto shortages (from denied coverage) and inflated market rates.
Other kinds of insurance are no different.
