Kudos to you to keep trying the civil conversation going, it's essential. I gave up because I came to the conclusion that there is no real motivation to discuss the issue at hand from core.

As Jimmy Song beautifully said "though couched in technical terms, the argument is ultimately an economic one".
I believe this can also be seen in core ppl being super willing to engage in technical discussion of this topic (they replied even to me for hours on this), but as soon as you try to include in the convo non-technical aspects (i.e. economic ones) they stop engaging all of a sudden. This happened systematically 95% of the time
