Why does reducing the proof of brain consensus mechanism from a crowd to a few people warrant applause?

The fact that there are so many delegators implies there are potentially many instances of PoB validators cough lazy rent seekers coughwhich will statistically make the outcome of consensus fairer than if the power was pooled together and elected via few persons as we still have here.

Step in the right direction but middlemen still need to be cut out. Proof of Brain doesn't function as intended when the voting demographic is more centralised.
