If anyone knows of a broker who will let you withdraw the proceeds (cash) of a short sale, I will buy the name of the broker off you. I'll also let you know why I would pay for this (although you may already know anyway, hah).

I spent a week researching this talking to fidelity, schwab, IBKR, and Robinhood, none would allow it.

I asked an adjacent question to a broker friend who flatly replied: "Not interested in being served a Wells Notice."

Which more or less answered the question for me, even if he was being a bit hyperbolic.
