No one can take it so long as you can actually play the media. I own a large music collection and I’ve used various optical formats for data backup for decades now. It is becoming more of a challenge, build your own computer and some cases don’t even have places to put that Blu-ray reader/burner. You can buy a couple extra devices and just keep them stored but in 10 years SATA connectors might be phasing out. There are real market pressures working against physical media. Live digital copies are easier, faster, more flexible.
