The locus of study is not the object of study. Anthropologists don't study villages (tribes, towns, neighborhoods . . . ) ; they study in villages. You can study different things in different places, and some things - for example, what colonial domination does to established frames of moral expectation - you can best study in confined localities. But that doesn't make the place what it is you are studying.
For anthropologist substitute experimental economist, for villages substitute laboratories.
