One of the things that people objecting to the US adopting healthcare policies that are successful in the rest of the developed world often cite is the desire to keep the US from being as regulated as other developed countries in healthcare.
The idea that the US is more regulated than "the rest of the world" in healthcare seems only to be generally held if you exclude the rest of the developed world from consideration; Third World healthcare may be more ripe for disruption, but disruptive business seem to not target places where there is merely low barrier to disruption, but also places where there is money to be made by disruption.
