Then you book what you can afford, and switch to what you want. It might make a difference of a day or two at the margins. It is at the margins, and swamped by larger effects. Or you borrow the 10, and if you can swtich put those 10 borrowed points into the AKV reservation, and bank an extra 10 forward. Plus, the resale owner who owns 150 is not booking the 160 point stay without borrowing anyway.
I just don't think it matters. I also don't think there is a horde of people wanting to switch from RIV to AKV and no one is buying resale RIV who might have otherwise done that routinely; they would buy something else instead. The problem with RIV is not the resale lock-in. The problem with RIV is that the Preferred/Standard point ratios are wrong (and too high). And that's setting aside the problem with
DVC generally, which is the studio/1BR point ratios are wrong (and too low).
I stand by my assessment: boogeyman.
