I would point out that this fact is *already* true, as ASNs are 
transferred through merger and acquisition all the time, and have been 
for over a decade.

I don't see anyone proposing a policy where an entity is required to 
return (and have permanently marked as unavailable) their ASN when 
ownership changes... I see, for instance, that AS 1 and AS 701 are still 
out there, despite the above happening several times, and yet nothing 
terrible has happened as a result.
