Until you remember that now nobody is going to be able to drink water from restaurants or their workplace or the tap at the park. And that you can't filter the vegetables you eat that have been watered with contaminated water.

Keep in mind, these restrictions have nothing to do with the environmental pollution but only the water treatment. So those veggies would still be contaminated with or without the regulation. If we moved to a paradigm of point of use purification, then the park, work, restaurant, etc would all have filters too.
