I don't know why we differentiate art from action. Some people intend for their actions to be consumed by others for a purpose of communicating or commerce, but there are no bounds to how little difference there is, theoretically, between any action and art - including inaction. Any constraints given to a "form" of art are illusory. Every constraint can be deconstructed and bent into meaninglessness. There are no forms, just our perception through living. We have the benefit of sensation - creating contexts and realizing patterns. This leads to valuing or appreciating certain presentations, but that's all arbitrary based on how we experience our existence. Art is a marketing term for what most of us would call living.
