Your moderating produces negative value.
The problem is that generic topics like "do we have free will" frequently balloon into large discussions that crowd out the more specific topic at hand. If we didn't moderate HN this way, HN threads would consist mostly of the same generic discussions repeated over and over. I'm pretty sure the community wouldn't agree that it "produces negative value" to prevent that from happening, even though we don't always make the right calls.
