If all my powered up coins were unlocked right now I would not sell them.
The delay has zero affect on me selling coins or not.
Again the delay greatly poor people while hardly affecting the wealthy.
If I want to sell $8k worth of Hive I only have to wait a week to unlock it.
For others that would but their entire stack and take 13 weeks.

I am also not suggesting we "open up liquidity", as a large AMM pool would suck up the liquidity into it and pump the price to the moon if the incentive to be there was decent.
