How do you know your bank's EV UI element has never been spoofed?  Have you,
every single time you've made an HTTPS request to your bank's website,
validated that the certificate presented for that TLS connection contains
the full and complete details of your bank, rather than a certificate which
contains the same displayed details, but differs in another element?

If you haven't done that, then you cannot say for certain that you've not
encountered such spoofing -- merely that you haven't *noticed* said
spoofing.  Which nicely demonstrates the insufficiency of the current EV UI.
