If you accuse someone of stealing the income, but they haven't gotten any money out of it, how does that make sense? What you're describing is a missed opportunity for a sale; had someone 'stolen' nothing and simply passed the product by, you would still not have made that sale and nothing would have changed.
The difference is one party at a time, i.e. household, library patron, etc, can enjoy the entertainment service.
When you pirate it, The original owner of the dvd retains the service value as well as providing the service to others without any value being transferred to the workforce/IP holders.
That's the difference and I personally am all in for a mythical solution that but still allows complete freedom of ownership while also stopping people from digitally reproducing assets and dispensing them exponentially.
I don't believe it will ever happen tho :/
