Agreed.
For it to happen it would take an economic meltdown of epic proportions.
Why is health any different to any other government re-distribution? It still involves trampling private property rights. Do you support an ends justifies the means ethics?
The level of acceptance varies with the individual hence why labels such as "fascist government" will only ring true to certain people. As more and more "fascist" type policies are implemented will more and more people agree with the label. I consider all government regulations as harmful overall so I am more inclined to consider certain regulations as fascist which you would consider acceptable. As another non political example, if you showed someone a complete chair and started to slowly take away parts of the chair, people would differ on when they no longer consider the chair to be a chair. I think the author of the article is speaking to like minded people so it wouldn't be as effective with people that have a different world view.
It still has a government, it just has a monarch that can veto its legislation, except for legislation to secede from the country or to dismiss the monarch. Not all libertarians are anarcho-capitalists, most are probably minarchists (small gov limited to defence/police/courts).
