Well, that does block many potential spam sources, and shouldn't
inconvenience the account holders since they all have smarthosts available
to relay for them.

No competently administered host does.  Unfortunately there are thousands
of incompetently administered ones around (mostly in Asia) and new ones pop
up as fast as they can be RBL'd.  Most of my spam currently comes via such
open relays.

Why not?  What they are connecting to is mostly ISP's POP servers, not
individual workstations.  Connect to mail.win.bright.net, deliver a
thousand spams, and move on.

$9.95 for maybe 100,000 spams?
