But you already know those feelings from being outside elsewhere. You get a unique combination there, but that's only worth so much.

> only worth so much.

Worth... quite a lot imo.

First, in the slightly objective sense of "What is this place like in real life, under X conditions." But, more subjectively, watching a video of a glacier and imagining the wind/rain/cold doesn't even approach 5% of the intensity and awe of climbing up a mountain yourself to see a seemingly endless expanse of ice, struggling to stand steady because of the wind, shivering because of the cold and rain. And finally, in the financial sense, a lot of people routinely spend many thousands of dollars and days-weeks of their time to experience natural wonders in real life.

There's so much natural wonder in the world in and around your home.

It's not that the value of the grand canyon is low in an absolute sense, it's that in a relative sense the gap between "empty numb void" and "hiking at home (plus grand canyon videos)" is far far greater than the gap between "hiking at home (plus grand canyon videos)" and "actual grand canyon".

Have you ever been to a place which is really high up? You're above the trees and can not only see as far as the curvature of the earth allows you to, but are high enough that the curvature of the earth allows you to see for miles. The air is thinner so it's easier to take a breath yet harder to catch it. Your sweat evaporates faster but a breeze doesn't cool you as much. The sun is brighter, rises earlier and sets later. The wildlife makes unfamiliar sounds and sound itself is changed. Even the same food tastes different.

It's not something you can get by sitting at home and changing the background on your computer.
