No. As I have pointed out to you before, with SegWit, all nodes that want to operate in a trustless manner require processing the signature chain as well as the 'blockchain-minus'. There is NO efficiency gain for a node operating in a trustless manner. What you call 'efficiency gain of SegWit' is only achievable by nodes that must trust other nodes to perform validation for them.
As such, SegWit does nothing for the centralization issue.
You quoted a post of mine related to LN and talk about Segwit? If you want to have a proper discussion join us at IRC; this toxic environment is fruitless and I don't even see half the posts in the thread anymore.
Threads should automatically lock when Godwin's Law is broken. It should be part of the software.
