Somehow this seems to be a confusion of categories: markets are real-world mechanisms, while P and NP are mathematical abstractions. Does not compute. To the extent that it does, it's typical mathematical macroeconomic BS.

We use mathematical abstractions to model real-world mechanism every day for millennia.
Not only that, but there are all kinds of mathematically defined limits that no real-world mechanism can bypass, from a purely logical perspective.
If you only have 10 dollars and I give you 20 dollars, you'll have 30 dollars, not 500 -- that's a mathematical truth that absolutely holds in the real world too.
Well, that's a quite insubstantial point, to say the least. Mathematical theorems place upper and lower bounds on what is possible in the real world within almost every domain. Of course, there may often be other reasons why something is impossible, too.
They don't need to exist in mathematics either, but the outcome would be the same. You can't do the real-world analogue of squaring the real-world analogue of a circle.
