I thought we were MAYBE heading that way in the days of iTunes but then the oh-so-convenient streaming came along and entirely killed the majority's desire to actually own movies.
At least music is a medium that managed to transition to DRM-free digital storefronts, even if it is barely used.
I guess it's not so much the discs I'm against (apart from the fact they do deteriorate faster than other types of storage) but the fact that there's no option to retrieve and backup the data on said discs. Although saying that, most games require huge downloads to install anyway so is there even any benefit or security in ownership of physical media if it's still useless without a significant download from a server than could theoretically cease to exist at any moment?
