Regulatory capture as mentioned in Shinobi's article https://bitcoinmagazine.com/business/bitcoin-mining-concentration-in-america

The concern I was raising was about deputized tax and KYC compliant cantillionaire mining companies adding endless amounts of their own hash at a loss to drive out all other miners until they own enough hash for their puppet masters to perform regulatory capture

Is this a realistic concern? It seems like an attack vector they are gunning for.
