The tail emission arguments can't be put to rest until we actually see, empirically, what the security budget turns out to be. Hashing out the possibilities in advance, and coming up with possible actions to mitigate catastrophe before it's actually on top of us, is the sensible response.

Faith-based assumptions that everything will be fine, because everything has been fine up till now, is about the stupidest possible approach to system engineering. I would have thought every bitcoiner would have this in their DNA, but it has not proved to be the case.
