The vast majority of DRM-encumbered media works probably have over 80 years of future copyright term applying to them, so a consumer would die before they ever need to crack the DRM and enjoy their access to the then-public domain works. On the other hand, works are entering the public domain every year, and some of these will be available in formats that are DRM-encumbered, so it seems unreasonable for Congress to have passed a law which effectively prevents people from selling devices that allow copyright to expire in practice.
