As a scientist, name one other scientific classification that uses numbers as a basis for the criterion of classification. It's especially arbitrary given it is used nowhere else in the continuum from dust motes to black holes.

It's a challenge you nor anyone else her has met and even Mike Brown who defends the new system admits is not a scientific motivation.

It violates the natural boundary criterion for classification. A number that we like is a human bondary not a natural one.

Human concept boundaries are for cultural definitions. A justification many have used for keeping Pluto a planet. A justification I disagree with. Making a definition that makes sense scientifically that is straight forward enough to be adopted culturally is the best solution in my opinion.
