Well for one you might but it will be incredibly expensive and probably still cover less than in the Netherlands. Also, the cost means that it is something you can only afford while you are still working. So if you do get hurt and can't work or get fired you lose that privilege. That is also a cost of opportunity that you lose by living in the US and that is not factored into the price of the insurance directly.
You don't have to keep working. Workers compensation, life insurance, long-term care policies all exist. There's really not much different in what's available, only who's responsible for it. In America, you earn and keep more and it's up to you to allocate properly (or not). In other countries, the government does it all for you to ensure there's a base level of support for everyone.
If you need to pay for a very expensive medical insurance then you can only afford it while employed which you won't be if you have health issues that prevent you from doing so or get fired.
