Really interesting! Tho it's not hard to envision a not-so-far future where these "stool-tests" are so cheap and automated that they are done in every street, then every block, then every apartment/house/hotel-room! Which can make sense from an urban disease-control perspective, i.e.find out who was the patient 0 of some disease. But of course then we will have stool-privacy defenders that will combat authorities so we can keep our intestinal activity private and un-spied at. Imagine the owner/worker of a hotel where {insert famous person name} stays, (s)he could potentially sell that person's sewage-test (directly from the bathroom pipes), to journalists or someone else. Haha.
