I could see Disney taking it over only for a PR reason
Right now, if you rent points, and something goes wrong, it's between you and the owner.
That alone must be a PR nightmare for Disney at times. Imagine a family showing up at WDW to find their DVC rental is messed up and the CM at the desk says "sorry, not our problem, you need to get in touch with the owner". Yeah, the family knew that going in, and it is the stated policy, but it still makes Disney look bad.
If DVC acts as the broker, they can make sure the deals go through.
or - to minmize the mipact
They could just encourage people not to rent points on a wholesale basis - as they do now.
