Your cartridges and discs are all that you "own" the data on them isn't yours and any slight damage to the storage media will ruin it completely

You've always been renting data, it's just the vehicle to get that data to your home was different in the past. You can back up your Steam games in 20 different USB storage drives if you feel like it. Fuck, you can burn them to DVD if you have a spare DVD burner from 2005 lying around.

Your Atari 2600 cartridges are legally yours but there's no guarantee you can play them in perpetuity. The slightest dampness and they're gone.
