The exact number isn't all that important. The number we pick should

on to at pennies per. Start at $1 and keep adding until only the
loonies say, "My cell phone should have a public IP even at that
price."

I understand that this is just an example, but it may not be the best one. Mobile carriers (at least the one I work for) already have contingency plans that involve categorizing mobile devices into those which can have IPv6-only (+ALG for IPv4), IPv4 + NAT, and those which actually still require a public IPv4 address, so that we can make sure we're using public IPs in the most efficient way possible, because we're pretty sure we're going to run out before IPv6-only mobile devices can do everything they need to in a way that's seamless to the end user.
Also, keep in mind that any suggestion of making it more expensive to have a public address would translate into something similar to what you see in some hotels - $X for standard service (which probably means NAT or ALG) and $1.5X for service if we have to give you a public IP. The transfer market might drive the same behavior, but you need to let the market decide what that pricing is, not try to artificially raise it beforehand.
