How do you know they are signed by the same key, if you do not have
the public key to check it with?

As far as accessing key servers telling people who I am
communicating with, they can get the same information by looking at
the members of the mailing lists I am on. As far as people I
exchange encrypted messages with, I didn't get their keys off a key
server.

But getting keys from a key server does not tell anyone who you are
communicating with unless someone puts a lot of effort into it. It
is much easier to watch the mail traffic going through your mail server.
