I’m a fan of the Capitalist Realist Shopping Cart Theory, myself.
Putting shopping carts away is bad for society and you should stop doing it.
The reason is that putting a shopping cart away requires labor, labor requires a person to do it, and the person who has to do it is employed by the grocery store.
Thus, if enough people refuse to put their shopping carts back, enough excess labor will be generated at grocery stores around the country that they will be forced to hire more people to do it, creating jobs.
QED
I think you could be right, but it depends on the details Nintendo comes out with. I remember people were saying that they thought certain Palworld monsters had been ripped from the Pokemon games and recolored - if Nintendo can demonstrate that, then that’s a slam dunk for them.
But if it’s just creature designs and collecting them, then I just don’t think that “a cute monkey with green fur” is a novel enough concept to be defensible against someone else doing something similar.
