For the current leg, and I repeat myself yet again, why was segwit better than simply doubling the blocksize? Nobody seems willing to explain that bit, for whatever reason.
Answer why doubling the block size is even needed at this point in time. With actual logic and facts to back your argument.
Because using LN requires opening channels on chain. To do this in a decentralized fashion, LN can onboard no more than several hunnert thousand peeps per day.
Several hundred thousand peeps opening/closing LN channels per day seems a bit overkill currently, don't you think?
Currently? Yes.
But I thought LN was supposed to be a scalability solution. And eliminate the benefit of bigger blocks.
It IS a scalability solution. Bigger blocks will (presumably) be needed some time in the future though, except not as much bigger as if Segwit+L2 were not in place.
You can argue developers will never accept a blocksize increase even when the need comes.... Well, that is speculation and I sincerely hope you are wrong in that one.
