> Wouldn't QE be anti-liquidity since it's net result is more cash goes to the Fed and QT be pro-liquidity since the opposite happens?

You have QE and QT backwards.

QE => fed builds up it’s balance sheet, it sends out cash.

QT => fed reduces its balance sheet, it gets cash back.

>On this earth, liquidity is about transaction velocity, and The Fed taking transactions off the table (by being a guaranteed buyer at every auction) makes non-Fed transactions happen at lower prices. The end.

Transaction velocity matters but it’s not everything. You’re myopically looking at one market, while the rest of us are talking about the systemic effects.

Transaction volume follows from the supply and demand for money. If you remove money from the system, you remove liquidity.

Look, you quoted a blatantly incorrect definition of QE/QT below. You clearly have no idea what you’re talking about.
