I dont't understand the analogy with rabbits, what with the staving and all.

Rabbits are plentiful and easy to catch, but they are not nutritionally complete. If you eat only rabbits, you'll go crazy and die

>If there are enough rabbits, the people eat till their stomachs are distended; but no matter how much they eat they feel unsatisfied.

Back in UK history there were paid rabbit hunters, who'd roam a farmer's land hunting rabbits. They ate a lot of rabbit. It turns out that rabbit meat is not nutritionally complete and some of them died.
