Umm, ARIN should provide a legacy holder with IPv6 space because the legacy holder doesn't care about ARIN?

Legacy holders have been holding parts (possibly more than they would be able to justify from an RIR) of a finite global shared resource without sharing in the costs associated, and it's unfair to _them_ that they're not _entitled_ to do the same in the IPv6 space?

Yep, makes perfect sense to me.  

If the "rest of the world" moving to IPv6 isn't enough encouragement for you, then bleh.   I'm only interested in encouraging my employer and my providers.  If you have no need to reach IPv6-only content or eyeballs, and you don't care about NAT or geolocation issues with centralized NAT or.... then sure, you have no encouragement or need to adopt IPv6.  If you do need to reach IPv6-only content or eyeballs, then that is your encouragement to play in the same playing field as everyone else in your RIR-area.
