For some people email may be much more important than financial
transactions. E.g. somebody may be OK if somebody snoops out that he
bought tickets to a concert (that 1000s of other people have done too)
using some throw away debit card where the balance on the associated
account is always 0 (he tops it up just before any transaction). But
somebody may want to much more protect what secret/private info he sent
to his co-worker/agent/family member. But yes, you can do encryption (of
your choosing) of messages in this case (which the communication with
financial institution does not allow you to!).
On the other hand, valid does not mean trusted. As long as the client
(FF/TB) does NOT warn you that the server replaced one valid cert
(signed by authority) with another (the current bad state). There is the
Certificate patrol extension for now, but this warning must be moved to
the core product. So in this case self-signed certs may actually be
better, as the client will warn you about the change (the exception does
not cover the new cert).
