If a miner controls an economy of scale (i.e. PoW hardware manufacturing), they ultimately control the liquidity/velocity flow of the State/Federal level cryptos that are derived from those root chains, given a lack of market competition. Therefore, direct influence over said monopolistic entities are then tightly-coupled to future tokenized cities/states, which means that entire political-monetary interfaces, globally, if adopted and built upon, could be centralizing governance in ways many might not immediately realize — until it’s too late.
