That's not his point. He's saying people buy pizza at night because they are unnecessarily working at night. Selling pizza at night shouldn't be necessary because its an artificially created market.

It's not artificial. I want pizza at night so I need someone to bring me pizza at night.

It is if the market wouldn't exist without people being forced to work at night. The difference seems to be very hard to understand.
