My take on this is the following. Everything we do as a society I think should be from time to time evaluated from a point of view of benefits for society/world and then depending on this evaluation, the incentives should be updated to support things that we consider useful, and to penalize things that we do not. A few years ago Bitcoin didn't really register there, and it was okay to disregard. Now with so much energy/efforts spent there, one should ask oneselves, is it good allocation of resources? Is it good that so much cheap electricity is used for mining bitcoin? Can we think of a way of either taxing, or changing incentives, so that society benefits from this. I don't know what's the best way of changing the incentives, but it must be done in my opinion.
