I'd imagine the vast majority of the customers of ISPs who are facing this
issue would react either with anger or non-comprehension if presented with
such a position. If you were running such a network, would you risk it?
Precisely. This proposition would result in both (1) increased support costs*,
and (2) irritated customers that decide to switch ISPs rather than renumber or
upgrade. We can't (realistically) expect ISPs to choose this.
The sad / funny thing is that result #2 rewards ISPs that use squat space or
globally unique blocks...

* - e.g. 30-60 min toll-free phone call with a technician, which might actually
cost more than the profit margin on some residential broadband services
