So why should any Crypto (including BTC) be worth anything ?
You are correct. But you won't find many agreeing with you here. Because there are only a very small number of coins there are enough fans that they managed to raise the price. The coin obviously doesn't work, it takes far too long to transact, costs too much and consumes more power than several countries.
One day they will wake up and smell the coffee but they will loose all their money first.
