>>20934263OK, usefulness is a subjective value. The value of the things you listed is subjective.
I'm personally not even a proponent of bitcoin, I'm more XMR leaning, but still it serves the purpose of a transaction method and it works pretty well at that. Offers stuff neither cash nor banks can do.
>>20934490That's still not intrinsic value, it is subjective value.
Even if all people in the world were to agree that something holds value, it would still be subjective value.
