Heh interesting idea, but I'm pretty sure the kid could be convinced to sell for $5000, probably much less - there aren't many kids out there that would scoff at multiple years' worth of allowance and lawn mowing money just falling in their lap. I think a market composed of people actually using the resource can set fair market pricing without the involvement of speculators. Domain speculators/squatters literally only drive the price of doing real things up.
