Ripping Blu-rays for personal use is copyright infringement in many jurisdictions. I'm not sure whether anyone's actually been prosecuted for it though.
It'll be interesting to see what happens in Australia. Not too many years ago, format shifting (eg CD -> mp3) for personal use was declared legal by the courts here.
The solution to that is what they're already doing which is moving everything online. I watch movies all of the time and I still have yet to watch a single thing played off of a BluRay and I know nobody who uses them.
Fortunately there will likely never be a way to stop people from ripping video and audio from a display.
