people should buy hard copies for the same reason you'd buy one of a really good album,because you want the physical satisfaction and connection to the object. It has nothing to do with money. When you factor in the cost of DVD production shipping, and promotion, it ends up being much cheaper to just release something online, otherwise, no one would release anything online. Add to that, the arbitrary purchases made on itunes, and the free marketing you'll no doubt receive from it, and you might actually save some money. All that buying a DVD, or CD, or vinyl is, is a self-indulgence, not necessarily a bad one, but one no less, because it separates you, (the cool person who actually cares), from the people who don't get it. Get it?
