“Why can’t I buy?” ≠ •Why doesn’t anyone sell?” ≠ “Why isn’t there a market for?”, not even close.

Why can’t I buy talent (in the sense of myself being talented at something)?

Because nobody sells it? There’s no market for it? Nah.

I’m an economist but the notion of everything being tradable on a market needs to be curtailed because it simply isn’t true.
