My two comments combined do not contradict what you say.

Thx for the link, I’ll look at it

OK. Natural prices exist as an unreachable ideal point, but there are no absolutely natural prices in real world. I agree, and, BTW, no ancap would argue with that.

there is no such thing as a ‘natural’ price.

Have you seen a middle-eastern market? Of the kind where they bargain. Like in fairy-tales.

That’s how markets actually look in the wild.

And the natural price is the mathematical expectation of the price you get by bargaining.

It’s very simple and in this particular case “mainstream” economics and libertarian economics get along pretty well.
