> Poop, bone, leather, wood re-enter the system very quickly.
I suggest you study the River Ganges and then reevaluate your position. Poop alone can destroy a river on the scale of citywide human populations.

Plastics are actually INCREDIBLE for preventing waste. A plastic bag for groceries is composed of roughly 13mL of LDPE, or roughly 260 "drops" of plastic! LDPE is so incredibly efficient at manufacturing that there's much less waste in its creation than textiles or other materials.
The issue with LDPE is that it doesn't biodegrade very gracefully and thus becomes a pollutant if its disposed of improperly. But from an engineering / manufacturing perspective, its one of the most efficient materials to make and manufacture.
In contrast, a leather bag required you to raise, feed, and then kill an animal. Indeed, the mammoth was likely hunted to extinction by primitive humans, and demonstrates that even at the small scale... humans can affect the environment.
And sure, the leather biodegrades gracefully (at least, more gracefully than an LDPE plastic bag). But you have to consider the environmental costs in creating the leather (water, food, and waste created by the animal before its leather was harvested)
