I can travel anywhere in the world mostly for free. How can I make money with this ability? Of course, there are the obvious choices such as import/export (which I don't know a lot about but would like to) and travel writing/photography, but are there any other things that you can think of? Thanks in advance for suggestions.

you mean besides the obvious and quite ILLEGAL import/export trades? It's up to you to be as creative as you need to. One thing you could try is hiring yourself out to go and scout antiques and other goods but not actually pay for them yourself. Just do it piecemeal for folks, like taking a camera with you and sending pictures back to people who may be interested and whatnot. That could just be one idea of many.

You could be an "envoy on board" courier - that's a job where you pick up a parcel, then get on a plane and personally deliver it somewhere.

You might try international express companies to see if they have openings for that or google "envoy on board couriers" and see what comes up.
