"The point is, that every pieces of art changes your whole perception of the rest of the world, for the rest of your life. And it's not a joke! And if it doesn't, then it's not art, it's a commodity."

-Lawrence Weiner

It's not necessarily the difference between what is art and what is a commodity. At this point in time, most types of art have become a commodity and still retain the ability to change your life in some fashion. In some ways, it's made to sell instead of being made just for the sake of creating, whereas its also made to make a bold statement. In today's world, there really are no limits. At any rate, I do think that art should be able to change your life or some have impact; it's just a question of how.
