Any time the basic premise is 'humans should stop doing the thing they've always done' you better have a hell of a mechanism to hold that vector, and the mechanism better keep working forever, or it's a non starter.

Literally no human progress has been based on 'we should be better'. It's been based on exploiting bugs in the human firmware to achieve some result. See: organized religion, the city-state, democracy, etc ...

Individual people can be rational and morally driven. People as a general population cannot.
