Waste of resources is self-correcting. If we were ever to run short of e.g. aluminium, scrap prices would go up and it would become worth selling old things rather than throwing them away.
Yes, but entropy is not self-correcting. We're wasting (as in, destroying, foerver) easily extractable material and energy. It's much easier to drive 10 000 tons of aluminium out of the mountain with trucks than to collect and melt enough scrap to get the same amount of metal for your factory from junk.
Economy is a leaky abstraction, it is ultimately subject to physics and it will break down if we push it too far hoping that market will correct all side effects of bad decisions.
