Because I pay ISP's to bring traffic to me.  If I announce the /32
everywhere, then I have to build and manage my own Internet backbone to
carry the traffic globally (in parallel with my internal/clean WAN).  That
amounts to paying two service providers to carry the traffic where I need
it.

It might be possible, but I'm looking for a solution that's more global in
nature that wouldn't require me to negotiate with tens or hundreds of
local providers.  One of the key requirements I asked to be put into the
multi6 requirements draft was that the end user would not have to maintain
business relationships / negotiations with anyone but his service
providers, so that an end user would not have to worry about maintaining a
business relationship with hundreds of service providers around the globe.
