The utilization argument about rental cars is valid when and if we get driverless cars. Until then, the amount that you pay the driver completely destroys that savings. (And in fact you pay for more wear on tires, gas/electricity, and other per-mile costs with rideshare, because the car travels more on your behalf than would a car you own.) How much house you want/need is a valid concern, but not one that really cuts towards the question of renting or owning your primary residence. You can buy a house without a guest room. I did!
