That isn't really how the judging worked though. First they had a huge panel of judges - 9 of them. And they judge them on 5 criteria: technique, vocabulary, execution, musicality, and originality. It is qualitative, but it's a comparative rating system with actual guidelines - so they each simply have to decide who did each thing better:

Maintaining physiological control while focusing on athleticism, form and spatial awareness.

The range of moves that display variation and the quantity of moves, ideally with minimal repetition.

The ability to land and perform moves smoothly, without falls or slips and while maintaining consistency and flow.

The ability to stay on beat, syncing movements to the rhythm of the music.

The capacity for improvisation, creativity and maintaining spontaneity with style and personality.

I don't think breaking necessarily needs to be in the olympics, but we're past the point of only allowing sports (looking at you, dressage) and we do have other artistic events (rhythmic gymanstics and synchro swimming). And, the scoring system for breaking was reasonable and able to determine valid winners.
