As a small data point. Back when I worked for IANA, I managed to
reclaim ~20% of the total IPv4 space. There are active discusions
in many quarters on how to ensure that the feedback loop is closed
and "dead" space is reclaimed for reuse.
Of course money is a great driver, but there are reasons to
have other tools in the toolbox, otherwise we could just run
the Internet on a big DHCP server and be done with it... :)
