And I would argue that it's not that Uber's supply expands as the price increases, but that demand slacks. Or at the very least both.
Delta can't add more seats within minutes by increasing prices. Uber can. Drivers can and do decide to put in an extra shift very late at night New Year's Eve because of the rate premium. That's where the extra supply comes from. It's real. If not for this large effect I would agree with your analogy.
