This is logic that suggests that any regulation of any major market is intrinsically "socialist".

Perhaps that's true, but if it's true it's only true in the sense that it illustrates how treacherous the word "socialism" is.

There is the saying "why own the farm If you can own the farmer?", which has been attributed to various totalitarians (and whose true origin I am unaware of), that highlights the fact that owning the actual means of production is unnecessary if you control the owner. This can be through regulation, corruption, or other means.

I don't see socialism as a 'treacherous' word, but 'socialism' is more a spectrum than a boolean variable. For instance, I am sure you are more socialist than I am, but that does not make you the same as Castro or Mao.

Careful.

I don't understand where you believe I am making a fundamental attribution error. I am an extreme libertarian or an anarcho-capitalist (depending on where you draw the line), and from what I've read in your posts over the last years, you are nowhere near that side of the spectrum(s), unless you usually argue in favor of things you disagree with.
