What do you do against intradomain routing problems? Loops? DDoS congestion?
Read my book, it's all in there.
With proper BGP multihoming you (as end site) can just withdraw your announcement via this problematic uplink. Doesn't help you with more-specific pseudomultihoming and people filtering the more-specific.
I appreciate that having your own prefix in the global table makes lots of stuff easier, but what if everyone wants this? It just doesn't scale. As for the DoS issue, your transit ISPs can create blackhole communities so you can have them blackhole the traffic for individual /32s (if desired) when those are under attack by announcing even more specific more specifics with this community on them.
