I don't necessarily like or agree with every decision made by Disney management...and there are many more that don't necessarily do me individually any benefits but that I can at least understand or appreciate. I don't agree that VLL is shortsighted or an emphasis on short-term profits.
First, DVC in general is not a "short-term" profit grab. Disney has realized that the benefits of having a "member" goes way beyond the short term profit injection they get from the initial sale of points. Members are very "sticky" in the Disney universe. That big initial financial commitment keeps them coming to the resorts on a very regular basis, in many cases increases their trip frequency to Disney World all while the same time ensuring blockbuster "occupancy rates" at DVC resorts. These all seem like long-term benefits.
Second, if Disney does go through with all the projects announced at
D23 (many of which are already starting to break ground) I think it shows a dramatic commitment to sacrificing short-term profits for long-term investment. Overall park attendance has been on a softening trend in the past 3-4 quarters. In the past that would have spooked management and provided a nice excuse to cut/delay/revise ambitious projects. While I expect there will be some tweaks, Disney seems to be going guns blazing into a very aggressive expansion of the parks on both US coasts. All of that should result in additional capacity and additional demand, which should be catered for in resort room growth.
Third, we are approaching 2042 when Beach Club, Boardwalk and Boulder Ridge will all go offline. Who knows what will happen to those resorts, but I don't think it irrational to start building inventory to compensate for that loss (even if temporary).
Now, all of that doesn't mean it's going to pan out how Disney anticipates or how they want....but I don't think it's a bad (or short term) business decision.
