I read that fellow's blog (marginalrevolution.com) and he goes out of the way to get the best authentic local food he can get, he's well read about the history of many different countries and the economic implications of the recent history (he's an academic economist). He often does a brief blog writeup about the particularly culturally unique bits of places after he visits. Part of his job as an academic/ popular econ culture writer is to understand cultures and economies around the world.

I don't mind if part of his motivation is to impress others, or if it's wasteful, etc. Why would his motivations have to be pure for it to be meaningful for him?
