Yes, I know the you're-either-a-lion-or-a-leech answer. But... back to the real, adult, interlocking world!
If there is "detriment" in play, then those affected must have (a) protection and/or (b) recourse to a just settlement. If there is "protection/recourse" there must be regulations in play. And regulations need a bit of nitty gritty in terms of arbitration, enforcement and sanctions.
Clearly, a society in which X, Y, Z, A, B and C live cannot simply rely upon the hope that X and Y will self-regulate and eliminate the "detriment". The only solution is that X, Y, Z, A, B and C reach some consensus about how "detriment" is defined and how members of the community protect themselves from it.
Imperfect perhaps, but what other mechanism could there be?
