The point is there is an "until" in there, meaning those people are not 
encouraged to waste addresses indefinitely because they'll eventually have 
to pay more.  Once you pass a /14, you _never_ pay _anything_ more no matter 
how much you waste.

Either way, the amount of address space an org has needs to be calculated. 
Anyone with a modicum of programming experience can tell you that it's 
easier to multiply that number by a fixed per-IP rate than it is to try to 
determine which of five pricing tiers the org falls into and return a 
different fixed rate for each.

I have yet to discover any argument _in favor_ of the current fee schedule, 
much less one that offsets its complexity, barriers to entry, and 
encouragement of massive waste.
