We have physical media on PCs, we even still have full control of them and can copy and modify anything we want.

Now you mean we should be buying some kind of disk which will actually offer us no more control and in fact was historically used for DRM.

Adding physical distribution overhead will definitely not help publishers (especially small ones or indie Devs) turn a profit.

Vinyl is horrible for consumers. CD was a format we eventually could use ourselves to copy and mix music to our preference.
