If agreements are in place with those other providers to carry the traffic, then sure.
Remember that when backbones peer with each other, they typically (and as normally dictated by peering policies on both sides) only announce their own routes and the routes of their downstream customers and agree not to announce a default route to each other. They do not announce a full routing table to each other. Upshot: When provider X de-peers provider Y, single-homed customers of either provider will likely have problems reaching single-homed sites of the other.
Some of it comes down to the mob-rule mentality. The hope (though not often publicized :-) ) is that the de-peerER will force the de-peerEE into buying transit from them to get the de-peerEE's customers to stop calling in saying "I can't get to site BLAH - FIX THIS!" The de-peerEE (or their customers) may opt to try their case in the court of public opinion and try to get the de-peerER to reverse their stance and stop being 'the bad guy' :-)
Irresistable force, immovable object. I now return you to your regularly scheduled programming.
