Well no, he is quite accurate. Aside from the Proof of Work and Proof of Stake technical pro and contra arguments we need to keep an eye on the regulatory side as well. Europe is going against PoW and just because they failed to have it banned this time does not mean they will not succeed in the coming years.
Please seriously consider: what is the value of a cryptocurrency if its whole existence depends on it being supported / allowed by nation states?
In my opinion, one of the main motivations for all this is free money. Free in the sense of freedom. If the ability of a blockchain to continue operation completely depends on regulators, your blockchain is doing something wrong.
