At its core bitcoin is #money — as defined by real economists. A real economist will tell you that money must be something that requires a non-trivial amount of energy to produce/procure, they call this "#hardness".
For thousands of years we used #gold. It had to be mined, and so the act of #mining it was proof-of-energy used, #proofOfWork, proof that someone valued it enough to use a bit of #energy on that rather than growing wheat, for example.
It procurement-'hardness' - not physical.
