You still have to deal with ETH fees just to get the funds into the roll up. I admit that ETH was revolutionary when it was invented but the insane fee market makes it a non-starter and the accounts model is just a preposterously bad (and actually irreparably broken) design decision for a decentralized network, makes Ethereum near impossible to parallelize since the main chain is required for state and the contracts that run on it are non-deterministic.
