The decision to make clones of himself was a tough one.
Knowing himself, Jimmy knew that regardless if he made one clone or himself, or a thousand, they'd all want to chase the same things that he did.
He didn't really care about his title as the tribe's Chief, he could live without it, but he was worried about the rest of the things, or people he considered his.
For example, each clone would want to lay claim over his girlfriends, and if there were a thousand clones who'd want to lay claim over them, the situation would devolve into a bloodbath where the clones would slaughter each other before they could get to his girlfriends to begin with. That wouldn't be productive, not one bit, so he was hoping to reason with them, assuming it was possible to reason with them, if he popped out a few hundred cones.
