Your point is well taken and as of today, seems quite valid. However, I think Marriott will set up a program where a DC week owner could resell his/her week and roll the points over to the new owner.
Marriott provides this service for the Asia-Pacific Vacation Club for a fee of $250. The owner sets the price of the total amount of points. When the Asia program was started, points sold for $0.75, then went to $1.00, then to $1.25. Their points are not sold on the same scale as the USA. 32,000 points would get you a 2 bedroom platinum week.
Recently, the points went back to $1.00 for a limited time. This happened after the launch of the USA program.
Long story short, today you can find many point packages for sale (mostly in Hong Kong) ranging in price from $0.83 to $0.95 per point. These are asking prices and I'm sure one could negotiate a bit.
The only thing that does not transfer to the seller is the ability to convert the Club points to Marriott Reward points. Everything else is the same.
Also, you cannot buy two point programs and combine them. You could buy a used program and add to it with brand new points. Or you could own one program and your wife could own the other (I would only advise this for the heavy-duty timesharer).
So, you are correct today, but Marriott will make it right for DC members. Marriott will enjoy making good money by simply shuffling some papers and typing in new names and addresses. Plus the opportunity to sell more points to that resale buyer.
Will the US point packages be worth 75%+ of the original cost like in Asia. Doubtfully for quite a while, but as the DC program evolves, it would seem the resale value would build if the program is deemed successful by its owners.
Please excuse me if the answer to this question is so simplistic that I must be terminally dumb for not seeing it but why would a potential new person to the Marriott system buy into the points concept? If I buy 25,000 points for say $23000.00 have I really bought anything of lasting value? I certainly have not bought anything I can reach out and touch like the deed to my weeks. Is it anticipated that the cost of purchasing these points will increase over time so when I go to sell them I would recover my value? I was told when I bought my first MVCI that I should be able to recoup my investment on that unit and it certainly has not happened. Why should this points program be any different? Since the resale value of these points is completely unknown why would I want to invest money in these points rather than just renting MVCI units as needed? If I am going to put $ into something I would rather have something concrete to say I own rather than a bunch of rather points. Marriott is certainly not going to buy my points back or help me sell them which then requires that I sell on the open market. I certainly would never recoup what I paid for them selling that way so it sounds like a losing proposition to me but maybe I am not seeing the big picture here.
