Well, they are actually pretty close.
Here’s why:
First, let me summarize your argument.
You agree that it’s OK to make you insure your car to ensure that third parties won’t have to pay for damage you cause. This is because you shouldn’t be allowed to choose whether to pay for costs you impose on innocent third parties.
You agree that it’s not OK to make you insure your car to repair damage you cause to it. That is, fundamentally, because you will bear all the cost of that damage. You break your car, either you pay for it, or you don’t have a working car. Nobody else has to pay.
I.e. You’re OK with making people buy insurance for costs they cause which others would have to bear, and letting them freely choose whether to buy insurance for costs they alone will have to bear.
That seems to me to be a fair summary. Agree?
Now let’s talk about body shops.
In the context of car insurance, there is liability cover (for injuries to third parties), and collision insurance (for damage to your own car). By your argument, people ought to be able to choose whether to buy collision, but it’s OK to make them buy liability.
Why is that? It’s because you can’t make anyone else pay for the damage to your car if you are uninsured, and don’t have the cash.
A auto body shop doesn’t have to serve you. If you can’t pay, they won’t fix your car.
So if you crash your car, and you have collision insurance, it will pay for the repairs to your car. If you don’t have collision insurance, you have to pay for the repair to your car. If you can’t afford to fix your car, it doesn’t get fixed.
If you have enough money for insurance, but not enough to fix your car, you get to choose between buying insurance, or not buying insurance–and hence, between getting your car fixed if it has an accident, and not having your car fixed.
That’s auto insurance.
Now let’s talk about hospitals.
If you get sick, and you have health insurance, you go to the hospital and (theoretically–assuming they don’t fight you on the charges, assuming you get all the paperwork in order, assuming there isn’t some omission on your medical records/application that the insurer can use to deny you cover, etc, etc,), your insurer will pay for your treatment.
So far, just like auto insurance. If you buy insurance, it covers injuries to you.
However, there is a big difference. An emergency room cannot refuse to treat you because you can’t pay them. It’s not like a body shop. Emergency Medical Treatment and Active Labor Act - Wikipedia
Now, what happens if you don’t buy insurance? Again, let’s imagine you have enough money to buy insurance, but not enough money to pay for treatment.
You go to the hospital. It has to treat you. It tries to collect, but you don’t have enough money. What happens?
Somebody else has to pay-the hospital has to pay for supplies, the doctors salaries, malpractice insurance (because you can sue them, even if you didn’t pay them)–it will do so by charging other patients more to cover the loss it just suffered, or the government will pay (through subsidies, etc.).
In other words, if you show up to a body shop and you’re uninsured, you are the only one who suffers the loss-either you have to pay, or you don’t get your car fixed.
But if you show up to a hospital, and you’re uninsured, the cost of your treatment will be put on other people if you can’t pay.
And that is exactly the kind of thing you have already argued we should be able to force people to insure against–costs you impose on innocent third parties. I’m one of them–I have health insurance. It’s expensive because (among other things) hospitals have to charge patients who do pay more in order to cover the treatment they are legally required to give to those who can’t pay.
The only way your argument makes sense is if we add one of two distasteful rules, so that you can’t force me to pay for your treatment :
(1) either hospitals can turn you away at the ER door if you can’t pay. Have a heart attack? Sucks to be you.
(2) or you pledge when you choose not to get insurance that you will never seek medical treatment you can’t pay for. Again, have a heart attack? Sucks to be you–sell the house, or die.
Unless you include one of those two rules, health insurance just isn’t like collision insurance for your car.
Instead, health insurance looks a lot more like liability insurance–at least for a basic plan–something that prevents you imposing the cost of your treatment on other people. And that is something I think we should be able to mandate people buy.
Now don’t get me wrong. I think hospitals should be required to treat anyone who comes in their door. I think we should pay for that treatment by universal healthcare, or an insurance mandate (combined with a subsidized plan for those who can’t afford market rates). We already are paying for the treatment of the uninsured poor–but now, they’re being treated at the ER–the most expensive way, rather than being able to get preventative care, and avoid getting sick.
