I think the issue may be that it is easier to objectively agree about what is bad than about what is good. With a collective effort like this, you don't want personal biases controlling this much SP. But I share your desire to see more curation of the good by high SP folks than all the focus on punishing the bad. It may just be that the latter is causing an existential crisis for the platform right now, so has to be prioritized in the short-term.
