freedom oriented expats, mainly Americans, to refuse the public insurance in those EU countries?

what??? "freedom oriented expats, mainly Americans"
If you were joking it would be funny but alas, I think you are serious. The more money you have, the more freedom you have and vice-versa. It is as simple as that! Given that a much larger % of the population owns a much smaller % of the wealth in the vast majority of the EU and the EU lumpen proletariat as a % of the population is much smaller than the American, the facts strongly suggest that while Americans generally may be far more impressionable and easily manipulated, they are most certainly not "freedom loving".
In the old days slavery was politically enforced while now it is enforced by the market. Workers
"who must sell themselves piecemeal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market." Karl Marx and Friedrich Engels: The Manifesto of the Communist Party
Anyway, please spare the little "freedom loving" speeches for elsewhere.
Insofar as the topic at hand, as far as I know it is a legal requirement that won't be enforced. I would help out but most Japanese people (who are obviously of an extreme right-wing political persuasion) posting here and a lot of foreign lackeys who have been beaten down and abused for far too long insist that the police have the right to stop, question and demand to see the I.D. of foreigners simply due to the color of their skin. Furthermore, I have to submit to finger printing (like a common criminal) when coming into the country. This being so, even though the costs are set to go through the roof and will be a tremendous burden on working people, I will decline to help out personally.
Of course if i were a "freedom loving American"
it may be different but all I need is emergency insurance as medical treatment is 100% free in my "non-freedom loving"
homeland.
