I agree there are beneficial uses for people who know how to control their files in the first place. But many users don't have that level of understanding, and with each concept comes its inevitable opposite. "Syncing" opens the possibility of being out-of-sync; and "access" could just as often mean "inaccessible."
Just my opinion of course, but In many workflows, and with the cost of "local media" as low as it is, ongoing file-exchange with the so-called cloud is an entirely needless layer of complexity and connectivity dependence.
