I doubt this would work. If you are not willing to pay for a CD,DVD, Software...etc why would you shell out on a monthly basis on the off chance that you are caught?
I, and about fifty percent of people I know, would be happy to pay a small monthly sum (say, up to nine euro) to be able to listen to and download any music we want, at any time, without risk of persecution. Ideally, this money would go to support the musicians, but that's not necessarily a requirement. Unfortunately, no such service exists right now - most of the music streaming services only work for the US, streaming's useless to many of us anyway because we listen to music in the car and need it on CD, spotify doesn't have half the musicians we like...
There's lots of grey area between "doesn't ever pay for any media, ever" and "I refuse to pay $ 12 for a single DVD with unskippable ads and warnings if I can get the movie off pirate bay in seven minutes, wtf".
