Thanks Stephen, and yes, I've heard that theory.  What makes people
'really' think the theory will win out over $$$

I'd rather be confident that the 'rules' that ARIN establishes will
indeed be 'enforced' within the community that really has the power.

What other mechanisms to empower ARIN to 'make the policies stick'

There is a theory that a non-trivial number of ISPs will filter at
defined prefix lengths, and therefore deaggregation beyond those lengths

will be pointless unless one only wants the block(s) for private use --

which none of us should care about.

Of course, if ISPs are willing to accept black/gray market /24s in /20 
space, they'll get what they've asked for (i.e. routers falling over).
