1 - You're worried about node centralization and in the same time pushing people to LN which in nature becomes more centralized with time.
I'm not "pushing people to LN". I'm currently not even using it actively myself (after some experiments in 2018 or 2019).
But I would use it if the fee situation of late April, or some months in 2023, became the standard, at least for some transactions.
For the "becoming more centralized" assumption, yes some big blockers in this forum continue to repeat that, but that's pure speculation. I haven't seen really research on that, if you know some, then please point me to it.
At this point I have wrote everything I think about current situation in Bitcoin.
I appreciate your time, the discussion was very interesting and good points have been made.
