If piracy leads to content providers leaving the market then we’re all a little worse off.

That depends. Would abolishing copyright lead to there being less content, or more content that was less well edited (because the financial incentive vanished)?

What I'm mostly paying for, with my monthly Virgin Tax, is simplicity. The TV is there instantly, and I don't have to faff around with filesharing technology. I'm happy to keep doing that - and I'd pay for all sorts of downloaded video, if the format was DRM-free.
