I can forbid you from polluting upstream of a section of river I own (hypothetically, I don’t own any). That’s a perfectly reasonable thing to do.

We’ve established there are ways and reasons for people to influence what happens on nearby land they don’t own themselves. Now we are merely quibbling over the details.

People need homes. They don't need to pollute

But we are not just talking about “homes” but “homes in a specific neighbourhood” and you can easily say they don’t “need” to live there in particular.
