You say you don't travel, but have you travelled before? Have you attempted to answer your own question experientially, rather than rely on rhetoric?

Because you could make the same arguments for basically any activity: would you reduce playing a sport or learning a craft as mere marketing by their respective industries, and make judgements on them based on philosophy, rather than just try out playing the sport or doing the craft for a while to see for yourself what it's like? Philosophy only goes so far, it's practice that allows you to become embodied in the activity and gain insight.
