I agree, although POA consensus is a more "centralized way" of validating a blockchain. If you have a good strong network of authorities (you won't find a better one than EWC) the benefits are unmatched. Like you stated high scalability, speedy transaction speed, low transaction costs and low energy consumption. If crypto were to be adopted my governments (or corporations like the EnergyWebChain) I'm certain this is the style of blockchain that would be used. Interesting fact, staking is coming Q4.
