Yes they are pretty big but many of those 5-6 DVD sets could be shrunk onto one blu-ray disk and actually would be cheaper to manufacture too
you can fit an entire season of most SD TV shows on just one blu-ray disk.
Some blu-ray's also use 2 or more disks though i think in some cases that is due to using single layer 25GByte disks.
But in any case get a CD-DVD pouch throw away the covers and you can easily fit 50 disks in a space the size of a hardcover book.
It's not bad considering 50*50Bg blu-ray disks that would be 2.5 Terabytes of data.
2.5Tb of blu-rays probably weigh less than equivelant HDD storage , less space , more robust, and water safe.
Flash cartridges cost way to much for general distribuition of high volume data.
The beauty of optical disks like CD, DVD and Blu-ray is they can stamp disks out at huge volumes for very low cost.
