Well, in that situation, are you likely to be someone who can afford to otherwise live in a single-family home with a yard? If so, you can move there. If not, your other option is probably just to be in an apartment without any sort of yard for your kids at all, which just seems worse. These sorts of apartments with shared spaces are common around the world. I'm sure they have some problems, but I wouldn't rule them out on the grounds that people might be horrible. And there are probably lots of people who would jump at the possibility of renting one of those places, assuming we build enough of them to make them cheap. And there are lots of other options besides those. You can have denser, but family-oriented development like townhouses, with narrow streets that slow traffic. Lots of parks and places your kids can walk to. Front porches so that people are likely to be out and watching for trouble (which as I understand is known to be an effective way to reduce crime in an area).
