LN requires orders-of-magnitude more block chain transaction bandwidth for peak garbage collection phases, than it consumes normally. Thus you need Bitcoin to scale massively before LN can scale massively.
Not really, no ("order-of-magnitude").
Bitcoin can't scale without being centralized for validation and mining. That is fact well known to experts such as myself. Many people may deny it and I have no desire to argue with them.
Even though that is correct ('can't scale efficiently'), the claim "experts such as myself" is really pointless in this context.
LN also requires a few numbers of centralized servers cooperating for it to function reasonably well:
Not really, no.
LN is an incredibly complex Rube Goldberg kludge patched on top of an inadequate block chain design and there IS a better solution coming. You have to discard the Bitcoin block chain and Satoshi's design and start over.
If by better, you mean partially-centralized scam coins that are being pumped, then you're wasting our time.
