A disc on a shelf is not perfect, but it is understandable. A digital item tied to an account, region, server or changing licence is different: you may have paid for access without receiving lasting control.
Sony removing or restricting access to disc-related features is a useful reminder of the wider trend. Hardware, software and media can be changed after purchase, delisted from stores, or made dependent on services that may not exist forever.
The answer is not to hoard everything or reject every modern service. It is to avoid a single point of failure:
- Buy DRM-free or physical copies when practical.
- Keep local backups of purchases and personal data.
- Prefer open formats and exportable libraries.
- Support creators directly.
- Learn which devices still work offline.
- Keep a simple inventory of what you own and where it is stored.
Convenience is valuable. It should not require surrendering all control.
