> the more material you put into your house, the less vulnerable it is I have a counter example about scale. The more material you put into a city (the more houses you build), the more vulnerable it is (more potential problems, more opportunities for crime, etc). While the house is less vulnerable than a tent, it can be secured for only as long as the flow of people and material through this house is very well controlled. The bigger squat house is not necessarily more secure. On a city scale free movement of people and goods is essential, and thus any place can be potentially visited (used) by anyone. We want the same urban infrastructure to be re-used by as many people as possible. There is a huge attack surface. Code is more like a city. We want the same code to be re-used in as many different contexts as possible.
