I think you're missing the point of this. To me it reads as a satire of un-selfaware privileged people and facile, feel-good travelogues. You can certainly be a traveler without being/doing either of those
I think you're missing what's happening here. This is a place full of exactly the people being satire: the self-awareness-lacking privileged people, as you say. They're being defensive of their choices, and arguing that they're not privileged at all, and anyone can do it, 'as long as they have the money and a job, which anyone can have', completely missing the irony.
