So... we absolutely agree on everything except two points:

1.	You see uniqueness as a benefit in the case of site-local
	(RFC-1918 which deprectaed RFC-1597) space.  In general,
	I´d even agree with this except for point 2 below.

2.	You believe that ISPs will do the right thing about these
	prefixes.  I believe that the moment ¨the right thing¨
	comes up against capitalistic greed, greed will win
	almost every time, especially if ignoring the right
	thing has no consequences.  If you believe me to be
	wrong on this point, please cite historical examples.
	If you need me to cite historical examples of cases where
	greed has won over the right thing, please consider:

	NSI site-finder (only removed because ICANN forced the issue
		and then, greed still didn´t accept the right thing,
		they sued ICANN over it)
	Microsoft embrace and extend strategy
	The reasons some of us are starting to regard it as IVTF
		instead of IETF

	This is a small set of recent examples from a much much
	larger historical set.
