A phone number is not an "envelope" -- it's routing information, just like
an email address. Publishing the email address is not in question and
there are alternative ways to find it out, such as search engines.
Oh really? Then you should be able to send a note to my gmail address.

And that distinction is?
To me a cell-phone number is a string of characters, and a public-key
is - a string of characters.
Finally, the properties of MY public-key will directly affect the
confidentiality
properties of YOUR envelope. For example, if (on purpose or by
force) my public-key
enables a covert channel (eg, weak key, key escrow, shared private key), YOUR
envelope is compromised from the start and you have no way of
knowing it. This is
quite different from an address, which single purpose is to route
the communication.
And if (on purpose or by force) your cell-phone number is being
monitored by an eavesdropper, MY call is compromised from the start
and I have no way of knowing it.
There is no difference.
