True competition can always exist unless force is used against someone to stop it (in 99.9% of cases, that's done via government regulation).
> the justice system
The justice system isn't an industry, it's a proper function of government.
> emergency service providers (think fire/hazmat etc)
As someone who has been screwed over by government emergency service providers, I beg to differ.
> Lets not let the bizarre state of the US medical industry act as some sort of straw man to support some ultra libertarian viewpoint.
Actually, lets. The US medical system is a total clusterfuck and is only getting worse. It is hard to get good medical care in the US. There is only one way this complete nightmare could have come about, and that's because people aren't free to act in their own interest.
We could never remotely approach this nightmare in any non-highly-regulated industry.
In fact, practically all non-highly-regulated industries make amazing advances over time, whereas healthcare delivery has seen amazing regress in the last few decades.
This is not an appeal to some ideology that is divorced from reality. The empirical evidence is all on my side, plus a causal explanation for the results. But liberals are covering up their ears and shouting, "We can't (won't) hear you!". As a result, my lifespan and those of my loved ones will likely be significantly curtailed.
