If I may add some to this discussion.
You guys are simply talking about 2 different things. You are both right.
A default route being generated by 1 router on the internet, and we are
talking Def Con 1. That same router on the otherhand, if it has a default
route configured for itself is perfectly feasable. Do you see the
difference?
To answer the original question, no you cannot generate a default route, and
I don't think you can redistribute a all 0's route into BGP , check me on
that one. And you wouldn't want to. BGP puts the default in the term
Default route.
On the other hand, If you had a BGP router, and were using some filters to
block AS's more than 2 hops away, you could put a default route on the
router, to cover the routing for all the other places on the internet. This
wouldn't be advertised to the internet it would simply be used locally, as a
gateway of last resort. As a matter of fact this is how I would prefer to
setup an internet connected router, even if I had the biggest fastest, most
memory router on the planet.

If you are looking or some kind of redundancy - i.e. have more then one
link, both solutions can work.
In most cases, if you're sitting as a leaf node and your network belongs to
the address space of your ISP
You don't need BGP at all.
My personal opinion. Kinda "Keep It Simple Stupid".

Sure.

To be clear - if you are connected to just one ISP - you don't need BGP at
all in most cases.
Speaking about the strange management - if you're unable to push them to buy
better equipment
for the task.....

Have you ever tried to run NT on a 386? Not just for fun...
