You aren’t wrong about Ks being bad. I agree they are bad, I just see them as a biproduct of something good.

if your hard hit rate increases so does batting average, OBP, OPS and with those metrics increase, so does runs scored, and Ks.
Over the course of 6,000 plate appearances, Ks increase at a slower rate than ISO or wRC+. scoring more runs is better than scoring fewer runs.
