I think the article has one fundamental mistake. "The miners' massive hashing work does not go into creating the bitcoins, but into stamping the ledger to (allegedly) secure the record of past transactions." This part is false. Each new mined block brings into existance new bitcoins. So hashing power is not just used to validated the new block on the ledger.
