We all now that there are other destructive industries, yes, of course we should talk about these too. But for obvious reasons right here what is it about? It is about blockchains - an industry that has not only extraordinary large energy footprint for what it achieves, but also has a very special property: nobody needs it.

Difference being crypto serves no purpose and nobody needs it.

People having needs which you don't even know about, yet they can fulfill via transactional exchange, are precisely why it's needed. If your fiat currency cannot buy it, but it can be bought, your currency has a bug likely built in as a "feature". Crypto addresses this class of bugs while your currency provider was established to create them.
