I think of travel as necessary if you want a true experience, catch a fish, ride a wave.
Climb that mountain instead of being one of a zillion with a selfie with it.
Yeah, but first you have to go to the mountain! That's the problematic part. I mean, look at how weird the Everest thing has become now - long queues to get to the top, wealthy people paying a small fortune to be almost dragged to the summit just so they can say they've done it. What really is the purpose of that?
Sure they've seen the Himalayas, but I've walked from Walthamstow to Croydon. Which of us has truly seen the wonders of the world? (hmmm....It's them, isn't it? Damn)
