look we can discuss a lot about what is expensive. But my comment was about that just a brute force "guessing" loop algorithm in PoW is being sold like a "Computation-intensive Operation" what in my opinion is just a stupid way to waste energy and belongs in the same club of institutions like Bank Industry and Gold Mining that also waste energy. PoS is loot better.
If the problem was adjusted where it wasn't using a double hash, and had some simple two-way function than it wouldn't be considered computationally expensive. That is irrespective of the length of the nonce. E.G if it was just a how much do I add to get a nonce of length x.
The complexity here is caused by the double hash.
The length of the nonce is just an even further scaling of an already difficult problem.
