What's the difference? (This is a serious question. Of course, I know some reasons why people think they are different, but I don't think the reasons that I can think of stand up to examination.)
If you design a system, then you can optimize it for different goals. A designer that's supposed to design a public space signs a contract. To the extend that the designer optimizes for different goals and especially goals that disadvantage certain people he's doing wrong.
From the perspective of a city written into the contract that the space is designed against homelessness also makes a difference.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
