If the original article's argument is basically correct then it means that for any alternative to PoW such as PoS compute-grinding work may be replaced by attempts to game the system or attack the system's security. I'm also skeptical of the claim that PoW is necessarily more expensive than fiat currency issuance. To account for the cost of fiat you must include the cost of all the security, administration, and governance that is required to enforce the integrity of the system. A dollar costs a lot more than the paper it's printed on (or numbers in a database).
