It doesn't have to be a public network to need globally unique addresses.
There is NO policy requirement to use NAT or RFC-1918 for private networks. Just a suggestion that folks be considerate of the community where they can.
I'll bet most of them would have no problem under current policy. They only need to show need for ~8,000,000 hosts, including subnet overhead.
If you wanted to, your medical company could have easily justified at least a /17 and probably a /16 under current policy.
There's really nothing to be gained from attempting to go after what might be reclaimed from the legacy block holders. EIther they will return their addresses or contribute them to the market or they won't. Attempts at forced reclamation will only make that situation worse and are unlikely to result in any actual reclamation of addresses before the conclusion of protracted and ugly law suits that would be very expensive. Such lawsuits are unlikely to reach conclusion before the need for massive quantities of IPv4 address space is in the past.
