ELI5:Why aren't digital movies way cheaper than dvd's?

For example: Say a movie cost $12.99 on Itunes or Google Play. Why? They no longer have to have a dvd manufactured which requires a factory and workers or have it shipped (trucks, drivers) or pay for overhead such as a store with employees to sell it. I realize there is still going to be some overhead cost but it seems like they should be way cheaper. So should songs too but I am more wondering about the cost of movies.

The cost to manufacture a DVD is mere pennies, so it was never a major factor in determining the price in the first place.  It's all about finding a price point that maximizes their profit.  Too expensive and not many people will buy it.  To cheap and they don't make very much money even when lots of people buy it.  Somewhere in the middle must exist at least one optimal price that maximizes their profits.
