It just looks ugly from the outside and would be pretty damn gloomy on parts of the inside without any natural light from that angle.
But that is not the entire point. The most important reason as to why buildings have blank walls, is because if they are built to afront a property boundary, one must assume that at some future point in time, the adjoining property may also be developed. Hence, it would be a waste of money, not to mention a fire risk, if buildings had windows on their property boundary.
