IME the cost savings of having a good piracy set-up (good = won't lose a ton of stuff on a single disk failure; streams well to your viewing devices in a way that normal people and visitors in your house can use without help) isn't even that large. I definitely wouldn't bother if I didn't have to have it to have (convenient) access to quite a bit of stuff I can't get any other way.

But once that's set up... adding more to it adds basically zero more marginal work, and when everything's in one interface the UX is crazy-better than any legitimate option on the market. So, may as well.
