This is about cashflow. Consistent cashflow at that. To achieve that everything needs some sort of subscription model. Rent is the subscription model for housing. These consistent cashflows then can be bundled into some sort of financial products and sold to investors -- something similar to the financial products during the 2008 crash. Just that now instead of interest payments which might crash, rents can be stabilized. Even if things go wrong equity is still protected due to the house.
