I followed this discussion a lot, and I resonate with your impression of it namely:
core devs are looking at it from a purely technical angle + economic incentive angle, but they are not considering AT ALLthe possibility of a malicious actor who only cares about hurting the network (and does not care about using more expensive ways to achieve this).
It almost fee like this "we already won and so we can do whatever" mentality has spread a bit too much....I'm worried about this arrogance/over-confidence, and lack of being cautious
