High-degree, high-liquidity hubs would be far more decentralized. You wouldn't need watchtowers, since the risk of channel theft would be meaningless when channels contain just cents.
Now couple that with low on-chain fees, so channels could be opened and closed much more easily and frequently, and the risk/liquidity barriers become quite negligible.LN has limited use-cases, but is not inherently flawed. I hope we will have it on BCH one day, because here it can actually work!
