Yes, but storing many TBs on several low volume disks is a PITA unless you can invest in a robotic library.

I wonder if Sony's ODA format could ever become more popular in the consumer market. I've never heard anybody mention it before.

Alternatively, I wonder if there could even be a "prosumer" robotic library system for common optical disks, something like a desktop archival data jukebox...

There are many examples of cheap self-build robotic systems (basically robotic CD changers). E.g.:

Yes, you definitely want sth like that. And further extend it.
