I don't think anyone is entirely privy to Disney's decision making. It's been speculated that there may be some promise to state or local lawmakers to offer discounted admission to residents. Or simply that Disney feels it's in their best interest to curry favor with locals. Those passes are blocked-out out on all but the slowest days.
That's been the conventional wisdom. Many businesses struggled during Covid but Disney did pretty well maximizing attendance despite whatever restrictions were in place. I can't speak to Disney in particular, but tourism is apparently looking strong for 2023 despite the lingering inflation.
If members aren't using their points, most are probably renting them. Or attempting to sell contracts they don't need. Ultimately there's someone staying in most of the villas. And the occupants are likely purchasing some form of theme park admission.
Overall I think it's probably a mistake to not offer some unique park admission catering to DVC members. DVC sales seem to be suffering to some degree. I find it hard to believe that a large number of DVC members are buying 2-3 sets of MYW tickets when APs are not available. I'd be fascinated to see whatever numbers Disney is working from if they suggest otherwise.
