I've said it a million times. nobody has a finished rollup yet. the development comes in stages. at stage 2 there are no more training wheels. it's meant to be completely trustless at stage 2 and until then stage 1 rollups still have escape hatches so your funds cannot be stolen or blocked from withdrawal. and the design would not coerce people into using custodians like lightning does because it doesn't use payment channels. rollups are a better foundation than payment channels.
