If you read enough of my posts you will figure out that I am a no pixie dust kind of guy. So I wouldn't say something like the "happiness" factor as you misquoted me as saying. What I am saying is that there are intangible and tangible benefits to owning. Some are a function of the system and others are perks that can be changed or removed at any time. But they do exist, and some of them can't be described, only experienced. I will say this, I currently hold reservations for boardwalk view studios for three Food & Wine weekends and a standard studio at BLT for the first week of December. I will not be making all of these trips, but until my schedule becomes more clear I don't know which ones I can or cannot make. When I figure it out I will simply cancel the reservations I don't need and use my points elsewhere. That kind of flexibility can't be had by renting.
In closing, I'll say this. Reading the arguments you make above, you probably shouldn't buy DVC. It doesn't sound like you're that into it. I also think you're suffering from paralysis by analysis. I think you need to make a decision and stick to it. Finally, an analogy. You can save a ton of money on ketchup by collecting the squirt packets every time you go out to eat or visit a food court. But sometimes you're better off just paying for a bottle at the grocery store. Granted, DVC is one big bottle of ketchup, but the thinking applies here.
Good luck with whatever you decide and thanks for an entertaining chat.
