Nice approach to explaining an IPO with the narrative, but I think it would be even more helpful to start in the beginning of a share's life when the company is first incorporated, when shares are created from nothing and assigned based on ownership.

How private shares are valued/traded. Really the difference between a private company and a public one with respect to shares/valuation/regulation.
