That’s not the point. Step away from the idea of one market maker intermediating a trade between a buyer and a seller who would otherwise miss each other. Conceptually, automated market making improves liquidity by enhancing price discovery. The markets become more liquid because prices become more efficient, and prices become more efficient because buy and sell opinions are much more rapidly absorbed into the market.

The faster the market makers trade, the tighter the feedback loop from buy and sell signals in the orderbook becomes, and the smaller the spread between competing prices.
