Coca-Cola zero is pure pleasure with no downside. It has zero sugar (that's a win in itself) but all the real great Coke taste too. In carbonated soft drink terms, it's the fulfilment of the ultimate male fantasy - unlimited enjoyment with zero compromise and no negative consequences. In life the best things are often spoiled by downsides - like perfect girlfriends with rules attached, independence accompanied everywhere by its evil called Responsibility - but Coca-Cola zero demonstrates that life does not have to be that way.
