AMM is superior to order books because the farming mechanic incentivizes everyone to all throw their liquidity into the same pool
No, it does not. It only incentivises suckers that have money they cannot put to use anywhere. That is certainly not everyone.
For some reason, people do not farm yield their cars. They could liquidity-pool their car and a bit of cash. Then they start earning and everyone is happy until the day they realise their profit is either a second car they do not need or worse yet, a pile of cash with nothing to drive.
The nature of cryptocurrency market makes it more bearable than the ad absurdum example but there is no guarantee that the incentives cover your losses that are anything but impermanent.
You can't just reject reality.
2 + 2 = 4
It's already happening.
It's already happened.
AMM mathematically provides more liquidity to the market on a dollar for dollar ratio.
People are using them.
These are facts.
Literally no one is saying otherwise.
Risk: meet reward.
Providing liquidity is far less risky than trading.
