Since you are a novice, don't pretend to understand and mislead others with long-winded arguments! V2 pool is a tax pool for discarded contracts, while V3 is a zero-tax pool. Everyone is trading in the zero-tax pool, and there will be price differences between the V3 pool and the V2 pool. When the price difference exceeds 5%, there will naturally be robots or others engaging in arbitrage. If the V2 pool has trading volume, it will generate tax fees. 50% of the tax fees are distributed as dividends, 16% are burned, and 20% continue to increase the thickness of the V2 pool. Let me educate you: go search for AVE on Google, and you'll understand why what you mentioned not only hasn't happened, but the V2 pool is actually getting thicker and has a significant trading volume.
