Indeed -- that's why it's called Pretty Good *Privacy*.
For the vast majority of people's day-to-day e-mails, they are not sending
secrets that could result in their imprisonment or other severe consequences.
Anyone who wanted to send such information to someone they could not trust to
use it appropriately would be rather loopy. Getting a trusted key for such a
person is the least of their difficulties.
Phil Zimmerman has said many times that PGP was written to increase the
general use of encryption. For protecting against passive eavesdropping
hoovers like Menwith Hill, even encryption using uncertified public keys is a
big step ahead of plaintext. The WoT adds an order of magnitude or two of
security, but still doesn't claim to be perfect way to send the most sensitive
information to anyone on the planet with no security downsides. Many of the
"problems" people are claiming for it seem to stem from a belief that it does.
