While your preference for physical media is duly noted, it fails to account for the evolving landscape of digital rights management (DRM) and end-user license agreements (EULAs). The legal framework surrounding digital distribution platforms like Steam is predicated on a licensing model, not a transfer of ownership per se.
Your concern about account lockouts, while not entirely unfounded, overlooks the myriad benefits of digital distribution, including but not limited to: reduced environmental impact, instant access, automatic updates, and cloud saves. Furthermore, it disregards the legal protections afforded to consumers under various jurisdictions' consumer protection laws.
In conclusion, while your nostalgia for physical media is understandable, it does not negate the legal and practical realities of modern software distribution. The non-rivalrous nature of software necessitates a different paradigm of ownership and access, one that the current legal and technological frameworks are still grappling with.
