A pressing concern for rollups is user lockin. As gas price continue to rise. More and more people will hold funds which is not economical for them to withdraw to layer 1. As an example at the moment a transfer in rollup costs ~0.01 usd while a withdraw costs at least 0.40 USD. This means that if a user deposits 1 USD. Sends someone else 0.40 USD then both will effectively never be able to withdraw these funds unless the gas price goes down. They can transact internally.
