Or it could not...
The availability issues are not just caused by renters and I think that there are multiple issues that are causing those availability problems. Getting rid of a few large scale renters won't make those club level rooms one iota easier to get because, imo, 90%+ of those rooms are walked mostly by legit owners who are looking to stay there. Similarly - the availability issues with VGF Deluxe Studios Resort View are not caused by renting - you probably just have thousands of relatively new buyers from BPK who prefer staying on the original building.
I do think you will possibly see some improvement, but likely not at the places where people hope the most. You really think that, even if renting was 100% banned, the AKV value rooms will last into the 7 month window? or the BWV resort views? There's a reason why the pro renters focus on those pretty exclusively - there is a lot of value there given those
points charts. That value may now go to owners, but it will still be mostly those booking at 8am ET at 11 months out, and those rooms will still be walked. Those looking to trade in with SAPs will not see much change, if any.
