I have no problem accepting physical cd playback, fine with co-existing. The problem is those who claim streaming is only for convenience, can't be high resolution solution. Also, some have strong sense of anger towards it, claiming its destroying our attachment to artists and music, like somehow the physical possession creates attachment a file can't. Seems something like religious symbolism to me.
And yes, we need to add cd rips to the equation, it too is played over a network so can be considered streaming to some degree. So, I do have over 2500 cds stored away, they hold no meaning for me, just clutter. Vinyl jackets on the other hand are wonderful, relatively large format. Cd's and their containers also bad for the environment, lots of oil to make all that plastic.
