I agree that DNSSEC is not the answer and has not lived up to expectations whatsoever, but what else is there to verify ownership of a domain? Email- broken. WHOIS- broken.
Let's convince all registrars to implement a new standard? ouch.

At that point, it doesn't matter how many vantage points you verify from: all traffic goes to your hijack. It only takes a few seconds for you to verify a certificate, and then you can drop your BGP hijack and pretend nothing happened.
Thankfully there are initiatives to detect and alert BGP hijacks, but again, if your organization does not have a strong security competency, you have no knowledge to prevent nor even know about these attacks.
