I would like to point out however that you are not really addressing edge effects at all in your lake example.

I wasn't trying to. Let's review.

It doesn't matter if the usage of my land changes the wildlife on your land.

More interesting are your opening three words: "It doesn't matter...". I would appreciate an explanation of why it does not matter.

That's what I'm responding to. I'm explaining why it doesn't matter with this example which is what you asked about.

Well, how about addressing edge effects?

The same analysis applies. What I do with my land indirectly affects your land. Too bad. So sad.
