1. Then why isn't there competition yet? This points towards a more complex model being needed.
2. I mentioned stickiness in https://news.ycombinator.com/item?id=11989391. But it makes the analysis more complicated, and the comments I was responding to were not at that level. Remember, I started by responding to a comment saying "There's no incentive for that profit to be passed on as reduced rates for the tenants.", which is a simplistic model.
I'm not saying the simple model is correct, I'm saying that you need a model which accounts for the things the simple model has. You can account for more things, and I did, but without doing that you aren't justified in complaining.
