Accidentally, an average price of a DVD movie is also around $20. So yes, there are places where fast internet is affordable, yet movies are not. Unless you want to watch only one per month and give up your internet instead.
There is also a matter of TV series, which you have to wait 1-2 years for (poorly dubbed) in TV or on DVD.
Of course we are probably in something like the top 10% of wealthy places to live in. I can only imagine that situation in poorer countries resembles the one we had when internet was just kicking off and hardly anyone had connection. There was (illegal) business model of downloading movies (from Kazaa or weird warez forums), burning them on CDs and selling for the locally acceptable price.
Guess what - unless the price of virtual goods is adjusted to the local standards, and the availability increases, piracy will be there.
