You don't.  However, if all you need is one IP address, a microallocation 
is less wasteful than a larger block.

Exactly what he said: the minimum allocation requirement.  If all you need 
is one IP address, justifying a /22 requires the making of, um, 
unsubstantiatable assertions, to ARIN analysts.  That's an unfortunate 
state of affairs, and one which this policy will correct.
