Because piracy isn’t a pricing issue, it’s a service issue. If people can get a better service for free, then that’s what they’re going to do. It’s the same reason people go to McDonalds, everyone can make a mid burger at home, but McDs has already done it and will sell it at a price some people will find reasonable. If I could go to Netflix, pay them whatever it costs right now and actually watch the content at a resolution I actually paid for and download to keep myself a copy for later (because again, I bought it) then I’d pay for Netflix. Seeing as that’s not the case and likely won’t be because people keep paying for Netflix, we’re stuck with the status quo.
