It's one option to resolve fine tuning. It seems extraordinarily unlikely that the there is only one universe and that universe just happened by random chance to have "interesting" laws of physics that are capable of chemistry. Either the universe is one of a large number of potential universes (anthropic principle + multiverse), or the laws of physics were designed or selected to be "interesting". It's not a falsifiable question at our current level of understanding of the universe, but it is clearly a question that has an answer even if we can't know it.
