I disagree, because many spammers work hard to remove bad addresses

In order to remove bad addresses (as Justin Mason pointed out), or honor
unsubscribes, spammers would need to supply either a valid return address
or a Web page somewhere that's trackable. That's the whole goal of all
the authentication proposals on this scheme.
You can't clean your list unless you can receive bounces, and to receive
bounces, you need to use a valid (and presumably somewhat traceable)
sender address.
