you also need ways for people to get liquidity without sending the price from 75 to 45. We had that in the past (there was actually a fair bit of liquidity on Larva Labs and price was constant from 60-67 for 9 months --- you just didn't have fake buyers being paid to bid)... but in markets you can't sell huge blocks to short-termers above market price, it would destroy any asset, but particular collectibles with no fundamental value and all pricing based on supply/demand. There are blocks teams on trading desks that do just this, take big blocks and sell at a discount and find longer-term holders. In the case of punks here, we had the opposite (above market to flippers) which is destructive.
