The high-trust Boomer brain cannot comprehend the actual low-trust society of grifters in which we live.

I don't agree with this blanket statement. The internet is low trust for lots of reasons, but regular (read small, proximal/spatiotemporally constrained) communities still exist and are not grifters all the way down. Acknowledging that distant strangers are not trustworthy in the traditional sense seems reasonable, but is categorically different than addressing natural social groups (small and local).
