Yes, indeed, they have sprung up all over DLR. We had never been to WDW, never been on a
DCL cruise, hadn't even been to Florida, but ended up buying DVC while at Disneyland. The Fastpasses they gave us for spending time at the sales center are now framed in Disney colors and hanging in the entryway as 'The World's Most Expensive Fastpasses.'
And you're only partially right about the home court advantage. True, there is no HCA re: west coast vs east coast, but many people on the disboards will advise that you purchase at the property where you like to stay. You can book at your home resort 11 months before your check-out day. You can book at other resorts 7 months before your check-out day. If your favorite resort is one of the smaller ones and/or you like to go during high season, it's often wiser to purchase resale than to purchase the least expensive or the one with the best deal and hope to book at the 7-month window.
That being said, we did purchase at SSR because that was where the best deal was. And we promptly purchased an add-on contract at SSR a month later when the Family & Friends deal came along. We had no problem using our SSR points to book at OKW during January. And since we tend to travel at low-season times, we don't expect to have problems booking into the resort we want when it's open for booking with another resort's points.
However, you will read lots of posts from those who are trying to reserve at smaller, popular resorts during popular seasons who are having no luck. 'Buying where you want to stay' is still good advice.
