No, that was the original claim. That you need the miners to agree. They are the ones that hold the computing power.

The claim I responded to says that in addition to this, you also need the majority of the "nodes", which are just computers that do no work and just forward transactions. This is incorrect, you do not need their help. It is easier if you have it, but you do not need it.

Bitcoin mining power is concentrated in China with about eight times the hash rate of number two United States, which in turn has a similar hash rate to Russia and Kazakhstan. Rounding out the top six, composing more than 90% of the total world hash rate, is Malaysia and Iran. Do you think these countries share the ideological goals of Satoshi Nakamoto's dream?

I have no doubt that a persistent 51% attack by a cartel of miners would make Bitcoin liquidity an indefinite hard zero for selected "owners" of BTC.
