Because I have to trust the DNS anyway. If the DNS redirects my users
to a bad site, they may not notice that they are actually entering their
personal information into the perfectly-SSL-secured www.bankofamerca.com.
Given the willingness of some CAs (which are trusted by browsers) to
give out certs with no verification at all, I am not sure there is
much to be trusted in the current CA-cartel arrangement, with the
exception of EV certs. So banks can continue to use the equivalent of
EV certs, and the rest of us who don't need an extra layer of trust can
switch to using root certs in the DNS secured via DNSSEC. The trust
hierarchy is already there.
I agree that there are two different trust models, one of which I am
required to trust and the other of which I don't trust at all.
