I think that most people love the idea of finding opportunities which others haven't discovered. Some take it in their own hands to leverage this advantage by products (e.g. app developers) others take a more collective approach (e.g. open source developers).

From how I understand the article Goldman has rediscovered a valid business opportunity that has been around for centuries. People always stockpiled supplies for later times and Goldman is doing it on a large scale. Even if they would be able to dominate the world market by this strategy, this situation would only sustain to the point when other material can be used as a substitute. So I personally don't see there a problem with this as long as they do not influence the market on the legislative side.

If there is a consensus among society that this is wrong, than it will be regulated. I personally condemn this increasingly popular idea that business should conduct self-infliction by neglecting opportunities just because certain parts of society disagree with perfectly legal practices.
