Would the world really be worse off without cardboard children's toys but also without people fighting over cardboard children's toys?

There is nothing about Costco that is causing the fighting.

It's entirely a unrelated subculture going insane about pumping up the prices of pieces of cardboard, and 30's-ish adults who never grew up mentally but now have disposable income.

Normal people buy whatever packs for the kids who proceed to play the game completely wrong.
