I am dreaming about a world where all movies and songs would be
available for free.

In this world, obviously, there is no place for overpaid actors, fat
middlemen, dull similar movies etc.

I am not sure how this industry would be financed.

I am sure that there would be less stuff produced.

The worst possibility would be proliferation of product
placement/advertising like "honey, you were so great in bed
tonight.. Yes, that's because I bought Viagra from buyviagra.cn". The
better possibility is that the cost of shooting movies would go down a
lot and they would be made because people want to make a statement and
can afford it.

But I am looking forward to the day when we do not pay for privately
viewing content. I do not mind that movie theatres live under the
copyright system, though.
