You have it all backwards. The PoW is useful work because it helps secure my hard-earned savings against very high inflation my country is dealing with (I store my savings in Bitcoin). While many other (non-PoW) energy uses you have in mind are useless for me.

there's plenty of other assets that can be used as an inflation hedge (e.g. precious metals, inflation linked bonds, etc)

none of which require burning hundreds of barrels of oil a day calculating quadrillions of sha1 hashes to keep their value from collapsing

and if you don't want to physically hold them then there's ETFs for that
