I do not suggest that. I merely ask you to support your jokey suggestion that the overhead of sleep is prohibitive when it doesn't seem to have prohibited ... anything.
If we didn't require sleep (and thus had 8 more hours each day we could work) we could produce far more as a race. It's not like it's some crazy suggestion, it's obviously true and unrealistic at the same time.
Without sleep, we would require one extra meal a day. A 133% eating rate is a significant increase in food required. You'll notice it when you stay up all night and it isn't adrenaline induced.
