RE: Cogent move without renumbering

Is it reasonable to think that numerous /24's from L3's IP
space could be
reassigned elsewhere without causing significant trouble for
L3 and others? Even
if it could work, what would be the justification for taking
L3's property?

Depending upon the circumstance, yes:

I think that is not entirely correct comparison. Original poster did not not say that the current L3 customers would entirely leave L3, but that
he asked if they could do something to get other type of connectivity if
they have L3 ip space.

The answer is that if they have /24 or longer and have router then they
can turn on BGP and announce that /24 both to L3 and to another ISP and
in this way have full connectivity. This would not be an attempt to take
ip ip space away from L3. But this is not something they could do within couple days if they do not run BGP and do not have ASN (takes at least a week to get it from ARIN).

(if i may shorten this a bit...)

Q can an "end user" take non portable ip's with them
to another service provider?

Depending upon the circumstance, yes:
