Your wording was ambiguous > In what universe does using encryption to evade the government function as a survival strategy? Could be read as either - It functions as a full and complete survival strategy or - One of it's functions is as a survival strategy The former is saying it's all that is needed, the later is saying it's something that can be used in that way (but not saying it's enough). Kind of like saying that food is a human necessity vs saying it is _the_ human necessity.
