Your edit is pretty much what I was trying to say. There is nothing inherently wrong with Socialism. The Reich's (amazing) initial success in WW2 was, in large part, due to its socialist aspects: state taking control of the industry, subsidized scientific research, etc., etc. It's the "Nationalist" part that made nazis ...unlovable. The whole racial purity, eugenics, antisemitism, lebensraum at any cost etc. The "socialism" part worked like a charm

A great many people DO think that there is something inherently wrong with socialism. It is an unnecessary and detrimental bundling of services into too-big-to-fail geographic monopolies.
Why does the insurance company need an army?
Personally, I am not well pleased by the unification of the entity that provides the survivor benefit (social security) also deciding how long I survive (health care). It seems a very clear conflict of interest with an abhorrent enforced trust.
The fact that the governance of most geographies have fallen into this trap does not make it more welcome or justified, only less so.
The only opt-out is exit and there are increasingly fewer of those.
