I've torrented physical media I've bought because it's more convenient and I don't wan't to pay the long term price of storage (either in terms of data or physical space). It's an interesting thought experiment: if I buy a DVD and physically keep it, am I more entitled to watch a movie in perpetuity than if I buy it and burn it in a fire. What if i keep the ashes? Where's the digital equivalent of a perpetual ownership structure? (For me, this all comes back to the problem that intellectual property laws/ concepts are, as a general rule, farcical/nonsensical)
