Btw the 1929 great crash was facilitate and exacerbated by lax Federal Reserve control of money issuance and the drastic tightening after the crash. This is actually an argument against centralized money.

I'd suggest you look up the Panics of the 19th century.

Well a joint stock company also does that. It engages in production. It does redistribute wealth. For a long time, public services e.g. firefighting, were provided by private entities. Is it socialism? I don’t think so. It has to involve coercion, say, via monopoly of violence to be socialism as it is a form of governing.

You obviously don't understand what socialism means. Socialism, by its definition, means involving government, be it local or federal. So, a private company is not socialism, a private fire fighting brigade is not socialism.
