In 2054, I'll be 88, my wife 90, my kids 60 and 56. They might be able to use it for ther grand kids. Even if they decide they no longer want it when they are say 50 or so, it'll be easier to sell a contract with 10 years on it rather than one with nothing. Sure there might be ones by then with 50 more years, but that will make ours a very attractive price. Let's say then a new 50 year contract (if they exist) is $1,000/point (that would only be about the same as a 5% annual increase). If we could sell our contract for 1/5th of that, it would still be a profit of about 100%. Even adjusting for inflation and maybe we still end up basically getting those 40 years for "free."
That all hinges on WDW being about as nice a destination as it is now, so of course there is risk.
