Route hijacking is theoretically preventable.  You have machines
verify the bonifides.  This does require that people take the time
to get the bonifides machines can process but we do have the tech
to do this.

Now we could continue discussing how easy it is to hijack addresses
of we could spend the time addressing the problem.  All it takes is
a couple of transit providers to no longer accept word-of-mouth and
the world will transition overnight.
