I regularly use my WorldMark ownership to exchange with ThirdHome and that is primarily what I use it for. There are others that do the same. It’s a good path to get into the high-end stays inexpensively. YMMV, though knowledge is power and that’s mostly why I post about that particular topic.
I don’t believe the purpose of the thread was limited to selling or renting points as a stand alone currency. My read was that it was to allow listings of ownerships that are deeded weeks or trust points that can be exchanged in the various points systems. Many of the systems listed don’t allow a transfer of points to third parties, so would have to be deleted from the list if that is its purpose. For example, HGVC used to allow transfer of points between owners but recently discontinued that and Club Wyndham discontinued allowing point transfers years ago.
You are correct that you aren’t allowed to rent out ThirdHome stays. That is no different than RCI or II exchanges made using points, though they are on the list.
