Hard copies of are good but there is an advantage of keeping digital copies; storage capacity. Physical books take up a lot of room if you have a lot of them but you can store huge libraries worth on a 1 TB drive. Just make sure you do it on an airgapped machine since OSes are becoming untrustworthy
I remember in 2007 Amazon erased 1984 from Kindles due to a publisher pretending to have the rights to it.
Piracy is the only way to maintain purchased copies of content from here on out.
Hard copy works just fine still.
