> Step 3: Now everyone begins shitting in the street because public bathrooms are no longer available. And those people shooting up in the bathrooms are also shooting up on the street.

I am having difficulties following. How did you get from step 2 to step 3? Since when does lack of available public bathrooms lead to public defecation? Is this really a thing somewhere? I cannot wrap my mind around it. Are people really this incapable of controlling themselves? Do they just let it go wherever they are when they get the urge? Horrible. This is not really the case in the country where I am, so "everyone begins shitting in the street" certainly depends on where you are, what the culture is, and so on. It sounds really alien to me. We already do not have available public bathrooms in many areas, but public defecation is certainly not a thing. People are taught to hold it back in until they get to a bathroom...

Edit: we also have fecal collecting bag dispensers, which is basically a bin (+ bags) specifically for collecting feces, usually dog. They are emptied on a daily basis. Take a fecal collection bag, put your feces inside the bag, throw it away into the bin specifically designed for collecting feces. No bathroom required, and no feces on the streets!
