I always thought they should have applied all the new DRM features to digital downloads only. In that context, sharing and selling does look consumer friendly and if they make it convenient consumers will move away from physical media.
Provided you had an analog communication channel and storage medium you could have analog downloads -- it would be similar to recording per-digital TV on a VCR. But, yeah, "digital download" is mostly pointless noise.
They used to broadcast software via FM radio in the 80s :) One could record the transmitted "noise" with their tape drive, and, apparently, more often than not the recorded program would actually work.
