Space isn't really an issue with Blu-ray and audio.
For example, the new Close to the Edge Blu-ray has 4 versions of the album in stereo PCM 24/96, one version in stereo PCM 24/192, one version in 5.1 PCM 24/96. AND space for another 5.1 copy in DTS-MA 24/48 and 4 versions of America (a 10 minute track) in the aforementioned formats and another set of bonus tracks in stereo PCM 24/96.
So what, like 6+ copies of the entire album in PCM and room to spare!
Maybe Universal just felt guilty using so little space on the Blu-ray format that they put as many different encodings of the same material as they could find.
But space does become an issue when you rip the album to hard disc. Optical discs are vulnerable to damage, loss or theft. Once on hard discs they become part of your regular backup cycle so should be as hard to lose as the rest of your backed up data. Hard discs are large, but they're not infinite and 25GB of blu ray space is significant. You'd only get 40 full ones per terrabyte.
