They don't mean much for egress filtering when the actor you're trying
to filter controls the software on both sides of your filter, but it's
fairly effective when they only control software on the client side of
the filter, as mentioned above.

You're going to have a hard time sending spam through a Tor exit node if
you can't connect to port 25, and you're going to have a hard time
downloading torrents if you can't connect to the BT port range.  You can
set your BT client to use whatever ports you'd like, but nobody is going
to be able to connect to you because Tor doesn't provide inbound
connectivity.
