I would like to point out that nothing about a "secret-key" system
prevents anyone from publishing an address to the world at large
which they allow anyone to make first-contact with them using.

That would work with exactly the same kind of spam-dynamics etc.
we have now.  But it would only apply to people who wanted it
to apply to them, and only for as long as they wanted it to
apply to them.  And anybody who contacted them via that address
would acquire a new address for them in the course of the
protocol, so cutting it short wouldn't cut off people who'd
already contacted you with it - all the ones you'd already
replied to would already have a personal address for you.
