This is exactly my experience as well, but there is a problem though. Most of people in the world just don't have a luxury I have - take a walk with my dog in the woods any moment I want. Most of people in the world don't have a luxury to switch environments in the way I have. Meditation is useful for people living in noisy (in all possible ways) environments they can't escape.

that's kind of exactly what meditation is. Not having a phone/tv/screen/book/human taking your attention.

And somehow pedestrian scenery doesn't take one's attention?

I think you are confusing meditation with relaxation.
