That's why you need new models to promote and monetize movies. Piracy without compensation is of course not viable, but so is not the current "overcharge for zero-cost-digital copy so we can pay exorbitant promotions for mediocre movies" (e.g. avatar's 1/3 of the cost was promotion)
You can't think that you are paying for a no-cost digital copy. You are paying for a copy of a production that took over a year and millions of dollars to create! You wouldn't argue that you should only have to pay half-price for milk because half of the milk company revenues were spent on advertising, right?
