This is untrue. Resale points can be used for stays at DVC resorts (including off property locations such as HH and VB), RCI exchanges and Club Cordial/Club Intrawest.
The restrictions on resale points means that you can't use them for
Adventures by Disney, The Concierge Collection, and The Disney Collection (
Disney Cruise Line is included in this group and is, therefore, excluded).
That being said, these options are not guaranteed, have limited availability, are generally a very expensive way to use your points and require large amounts of points. It's basically like saying that if I buy a used car I can't attach a chainsaw to it and use it to mow my lawn. No biggie, I wasn't planning on doing that anyway.
