SMTP server (which should have a proper RDNS record) and get on with their lives? They can still
retrieve their email from their Exchange (or whatever) server....why do the NEED to send through it for
outgoing messages?

As I mentioned I represent a significant number of small businesses. To them the price difference is significant. I'd LOVE for them all to ante up and spend for a T-1 or other high-grade data circuit but it won't happen. Others have already made the point that there is NO RFC out there that specifies what connection type is better than another. Even blanket blocking dynamic ips in general doesn't sit well with me. I choose to have scripts that analyse our mail logs and any IP that generates spam (theoretically dynamic or otherwise) more than 5 messages in a day is added to an internal blacklist never to be heard from again. The list of ips is getting larger on the order of a thousand a day but at least this way I can justify why someone gets rejected rather than saying "well...this RBL said I should".
As far as "IT stragegy". The "strategy" most of these small businesses implement is hiring a hopefully qualified consultant or consulting company to get them set up and running. Admittedly we're called in in many cases after a so-called competent vendor set up a system that relays etc etc but still after they are set up properly they are just like any good netizen and deserve to be treated as such. Certainly the systems we install ourselves do not relay and for someone to say something like "if you live in a crime infested neightborhood just accept getting shot at" belies a rather arrogant attitude toward the people who care and do it right the first time around. Making up your own standards as you go along is rather Microsoft. Show me the RFC that says it's OK to block these people and then we'll talk.
(stepping off soapbox and going back about my business).

"hosting" often means a hosting provider who has put in place, at great $$$, all the infrastructure, including the WAN links, to assure continuous service and/or shortest, infrequent service interruptions.

If an individual or small org, very probably without the competence to run a mailserver and DNS, wants to risk his mail/DNS service on a cable or DSL WAN link which have no SLA, that's his choice.

There's no need to be excluded, just relay your outbound through an IP which does not have a subscriber-style PTR.
If you are in crime-dominated PTR neighborhood, expect to get shot at.
