I had this discussion with Khal on discord yesterday, and I thought it would be better as a video.
In the very worst case scenario, everyone dumps all their LEO earnings and the buyback program is the only buyer. We would need 11k of ad revenue daily in order to make that work out to 2 USD/LEO. And that would mean we need to grow our userbase by 700x. Tough, but doable.
Currently market prices are 40x above that worst-case scenario, so we would need to grow users by 35x to hit that same number with a more realistic market.
