Barely any of the people involved are mods. I said that repeatedly before your post yet you chose to ignore it, despite apparently singling out my posts specifically for consideration.
Objectively, people are nicer now. Informal policies turned into a proper Code of Conduct over time and moderators (the actual moderators) take it very seriously.
Being strict about this is objectively correct and it has absolutely nothing to do with power tripping. Nobody wants to close and delete questions. They want those questions not to have existed in the first place, or rather to have been asked properly in the first place.
The system does not incentivize any of this curation effort; it happens entirely thanklessly and driven purely by intrinsic motivation to produce a specific valuable thing.
This is not a matter of "bureaucracy".
As far as I can tell there is no issue with site traffic:
