Buying stuff we don't need because of far-fetched edge cases creates insane amounts of pollution.
Most of those far-fetched edge cases have simple solutions (such as renting).
I can't count the massive amount of stuff we have at home and don't use at all despite my active pushing against those, literally everybody I know is in the same situation.
If we reason like that capitalism will push us further into buying and buying because what if.
Car rentals and Airbnbs literally are the answers for both.
