Guess what, networks evolve and have been evolving for as long as I've
been involved which is around 30 years now.  There is no reason to
expect that they won't stop evolving for the forseeable future.

So you have no idea if it is a significant income stream or not.

Except it is not just the accounting and billing systems. Additionally
when you factor in everyone is getting multiple GUA by default the
number of customers that need to pay for additional addresses drops
by orders of magnitude it doesn't remain cost effective to charge
for address space.

If you are being charged anything to get a /48 over a /56 or a /60
you are being ripped off.  If you can't get a /48 you are being
ripped off.  The public will learn this as will the regulators that
protect customers.

There actually is a IPv4 address shortage.  There isn't a IPv6 address
