Collector items exist, and while a certain amount of resources have to be burned to preserve them, on the whole, they seem to me like a positive effect on the environment.
Say there is an old Bugatti that rich people trade for tens of millions of dollars.
That is basically a token, and the cost to society is the original manufacturing cost plus the upkeep.
The inflated market price is a good thing, because it represents the potential consumption that rich people are not consuming and is therefore available for the rest of society.
On the other hand, if someone spends the same amount on a brand new yacht, then they are putting all that value into environmental impact, either directly or indirectly. And they're taking it away from all the poor and hungry, even if the yacht builders benefit and it "trickles down".
It's exactly the same logic as the famous Eisenhower speech about national defense taking away from the needy.
One simply needs to make the mental transition to considering all wealth the property of society.
Most people seem to have it all backwards, where abstract tokens and bank accounts are a waste, and consumption is "creating jobs" which is good.
Crypto, as far as I can tell, neutralizes things through requiring undue consumption to create the tokens, so it seems to me like a massive step backwards.
