Some like to argue the point that renters don't affect anyone by getting rooms at prime dates as the rooms would be occupied by someone using points, either their own or using someone elses. The arguement being that owner's points used at the 11 month window have every right over all the rest. Not a very fair way to play the game, especially if that owner is spreading points over many units during the same dates. Other than Grand Gatherings type of vacations, one owner with alot of points should not be blocking other members from their right to book rooms, and that is essentially what happens.
If that is truly the case then your conclusion would be that large point holders are bad.
Large point holders often spread points over the peak times, whether it is for themselves, family or "others".
Is it your assertion that possibly the maximum number of points one can own should be reduced?
I'd be OK with that for sure and it would reduce the liekelyhood of people getting points with the sole intention of renting for profit. There would still be loop holes but those could be plugged fairly easily.
Everyone has a right to use their points to book during the 11-8 month window at their home resort. No matter how many use the "renting is bad, Commercial bad argument" it does NOT change this fact. So if you truly feel renting, commercial or other wise, is bad then we you need to come up with a better solution.
