Amusingly enough, I personally (along with others) made arguments along these lines back in 1995 or so when the IAB was coming out with http://www.ietf.org/rfc/rfc1814.txt.  Given the publication of 1814, you can probably guess how far those arguments fared.

(and likely flag you as someone to whom address space should never be assigned.)  The only reason legacy holders get away with such crap is because there's no clear contract governing their assignment.

I haven't looked recently but I believe all the RIRs have policies that requires them to allocate unique numbers regardless of whether those addresses will be used on the Internet, as long as the requester documents appropriate utilization.

I gather you're volunteering to pay higher fees to cover the increased legal costs?
