"I do expect most of the category of thing that worries me to be handled by polities preemptively exiling daeva. But if there's, oh, a wildcat Lunar arcology, with a park in it, and the furniture angel comes to the park, she'll be recognized, and all the kids will have to go home, instead of playing at the park. Making her give them ten feet of space doesn't prevent that. It doesn't even prevent a toddler who doesn't know who she is yet from running up to her and their parent having to also run right up to her to get them away. Making her give everyone ten feet of space while she freely roams every place without enough of a government to fence her out is already falling so far short of making people feel safe and comfortable, here, that I'm not sure what to do to impress that upon you. Making it even worse than ten feet, even closer, even more of the possible proximity initiated by her instead of confused children, that's a very hard thing you're asking."
