There are such people and they have Youtube channels. However I wouldn't underestimate the desire of geographical exploration just yet. Even if you can easily travel everywhere this ball we live on is still bigger than any single person can explore in a lifetime. Give me a single city (I'm a city person) in another country where I can stomach the food and exercise the language and I can easily spend a year before I get bored. And I bet there are more than 80 such cities on this planet.
