I strongly disagree with that statement.  No matter your thoughts
on IPv4 and IPv6 one of ARIN's tasks is to be a steward of IPv4
space /for as long as people wish to use it./

There is a long history of new technology eroding existing markets,
but rarely does it make them go away.  More importantly, technology
that is not useful in one market may be huge in another.

Venezula uses lots of Ethanol, the US does not.  This despite a gas
crisis in the 70's, and numerous alternative technologies.  Digital
downloads have not stopped people from selling CD's.  VoIP has not
forced AT&T and wireline phone providers out of business.  There
are companies out there still making steam engines and buggy whips,
if only for much smaller market segments today.
