I think that was William's point.

Both are questionable, it's just a matter of degree.

Unfortunately, since address allocation policy is subject to the whims of the public policy definition process there is 
a risk (e.g., the proposal to allocate /24s of IPv6 if you knew the magic word or the proposals out of the ITU to 
allocate country blocks (/8s have been mentioned)).  There is no finite resource that people can't waste.
