The argument is essentially that the computing and hashing power has intrinsic value for other use cases it could be reapplied to if not doing this. It could, but that value would accrue to the person selling the energy and/or the hardware, not whoever held the token at that time.
If you think about it, what you actually mean is that you don't recognise the utility, not that there isn't utility there. If we do a classic comparison with gold, pretty much nobody gets any utility out of the gold, and yet a tonne of gold still has very high intrinsic value because it has just enough utility to some rare people.

That isn't how anything else works. Little of the value of the economy accrues to the people who mine coal or oil, but they provide most of the raw grunt to make all of everything work.
The economy doesn't have to directly link creation of value to who gets rewarded.
I wasn’t comparing anything to gold (or whatever other asset). The energy expended is cited as a reason for the value of the token, but the utility of that energy, even if it were a near infinite amount, is still zero, because it’s already been expended. It’s a fully sunk cost.
The magic that people try to conjure by saying the cost of mining means it’s valuable is provably not true. That energy isn’t stored as value in the token, it’s gone.
To use your analogy - I’m not saying the value accrues to the miner of the coal/gold/whatever. It accrues to the owner. The asset in this case is not the token, it’s the energy.
The re-deployment of that energy to other use cases is not a transaction between the purchaser of the energy and the owner of the token, it’s a transaction between the purchaser and the energy company. In dollars.
While at a theoretical level different crypto tokens are the same that will not be how the market plays out. That sort of computing power isn't easily replaced and while it exists Bitcoin is unique. So it does have value at the moment, but the value is not inherent in the protocol.
