>markets are real-world mechanisms, while P and NP are mathematical abstractions

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.
