Your quality of life is horrible. You have paved over, fenced, destroyed nature. The right to camp is self-evident and unalienable. Cities should buy back at least 50% of land for the public to usufruct on. Teach, encourage, facilitate leave-no-trace ethics: provide garbage sacks, recycling bins, mops, brooms.
You are the real problem. Your rapacious, ignorant, casually cruel greed is destroying natural rights of animals and humans who reject your perverted, insidious system. Please move out of cities. We don't want you there. Have you considered Mars? I'm sure you can afford it.
