Only a very small subset of the population torrents movies. Look only to redbox, Netflix, Amazon, motion picture producers even cable companies to see they are all posting huge revenues. Your assment seems to be based on your friends, not the market at large. (Notice I said Rev rather than profit as revs show that people are paying.)
I'd rather pay 8 dollars a month for hassel free streaming and millions of other people would too. This is big business.
