The idea behind EV's (to tie domain ownership to real-world legal entities) is sound, it's just that the implementation is poor.
If the EV badge identifies a legal entity plus its country of origin, then how is it supposed to be the CA's fault that there's this leaky abstraction of multiple legal entities with the same name in the same country? If we have a good idea and a poor implementation, then the correct response is to fix the implementation, not throw out the whole idea as fundamentally broken.
Unfortunately, there's also not much that the CAs can do to fix this by themselves. If we want to have a digital representation of a legal entity's identity, the best way to do that is to have a first-class digital identity rather than the hack of a system we have today which attempts to create a poorly supported, non-portable identity on the basis of emailed paperwork and phone calls. Such a first class identity - with private keys controlled by the legal entity, entrusted to the entity when it was first created - will allow clients to verify the identity against the source which actually governs it.
I can understand the privacy concerns surrounding the creation of legal digital personal identities - the creation of a definitive population ledger that goes along with it etc. But for companies? That the US doesn't have such a solution for companies in this day and age is just myopic.
