I didn’t say commodities traded on Wall Street, and I know usually they’re middlemen.

I’m saying Wall Street banks are the kinds of investors to sell delivery contracts and then find a way to gather water cheaply and actually deliver it (for a nice profit). Banks aren’t always just middlemen.

The contract is cash-settled so there's no opportunity to pipe in water like that.
