DeFi order book models have long promised liquidity for a wide range of options, but this simply hasn't eventuated yet. The AMM model offers instant liquidity using a model that is instantly scalable and generalizable to many different assets that are currently underserved or untouched by the order book model (i.e. any non BTC/ETH asset), even on CeFi exchanges like Deribit. The AMM model can be iterated on to converge on a solution which ultimately offers LPs flexibility, whilst preserving the instant liquidity that has been the reason that AMMs have seen explosive growth in DeFi to date.
