You're still thinking of exceptional cases. Photo managing applications have, and will improve, native ways of sharing the photos, even if it's as simple as sending an email.
I see no reason why making the common case simple (not "dumb") means you have to eliminate, or even alienate, the power users. Frankly, since I started using a Mac, iTunes and an iPhone, I stopped managing music files. And I think that's great. Files are an implementation detail. What I want is music or radio programs, not files.
It's an error to simply transfer "it works for music" to "it works for everything". That it works for music is largely because sharing media files is verboten in our Brave New World - sharing is not a problem that needs to be solved there. But sharing non-media files between users is not an exceptional case, not even remotely - it's common as muck in business.
The idea that the 'normal' user is only a home-based casual web-browser/photo-taker/music listener is misleading from the outset.
