The way I am seeing it is that you would no longer share the values of your society. Or maybe it is just my society being in the USA and being so materialistic. Materialism is promoted so heavily here because it is our driving force behind our economy. People are so attached that I would think it would be hard to relate well with many people. That is not to say that you cannot interact with them or live among them. But I guess if you reach true enlightenment it would not matter?
