Because there aren't any beachfront lavatories?
The sea is already salty, so....
****The question is “why?” Why do so many choose to relieve themselves in the ocean as opposed to making the journey across the scorching sands, over the sleeping homeless and into nearby beachfront lavatories?

Correct answer is that the queers are in the beachfront lavatories. Because of their nasty behavior, the uninfected only go in those places with a full exposure suit on.
No public restrooms. If you walk off the beach and cross a busy street to find a bathroom at one of the local establishments, you will run into "for customers only" signs. So you need to buy a hot dog or a slice of pizza...or you could just wade out into the ocean to waist-level, put your hands on your hips, and pretend you are admiring the horizon.
