Here's an alternate theory to explain the promises of 100x miner revenue:
What if the expected configuration is that miners themselves become the big LN settlement hubs?
In an environment where you're redlining blocksize capacity, the only entities that have reasonable assurances of being able to enforce channels are miners of a certain threshhold size (based on the length of timelocks in question). So either the large hubs have business relationships directly with certain miners, paying out-of-band, or the actual hub itself is a miner, either way it probably doesn't matter, pretty much the same result.
If this is the case, then all of Peter Todd's uniquely schizoid FUD stories about what regulators have supposedly told him and only him suddenly start to become plausible, because if miners become the new banks, then that's a very clear entry-point where regulators can start asking for AML/KYC on the mining itself. Or even worse, because they can just start censoring every transaction that isn't known to be part of their little settlement club, and then AML/KYC at the endpoints takes care of the whole thing. Legendary Internet Idiot Professor Bitcorn literally submitted hand-written notes on the first Bitlicense draft suggesting requiring licensure for miners. If alot of big miners end up being custodial off-chain wallets that settle over LN between each other, then agree or disagree, but Prof Bitcorn isn't exactly a total idiot anymore. BTCC in particular looks like it's setting up the infrastructure to do something very much like this.
