Well, one can use a conventional torrent client. Half of the popular ones have some kind of “share mode” to automate the creation and link exchange. Or use a dozen other existing file sharing tools, including plain netcat.
The problems are elsewhere:
a) “Simple enough” is a moving target. Some time ago, users were expected to state their needs, find convenient tools, figure out how to use them, and be happy that their problem is solved. Nowadays it is proclaimed that user is an idiot, because the idiots don't actually choose anything, they do what someone else decided for them to do, and it's Good for Business.
b) People don't know which solutions already exist (looking at the author here).
c) Smartphones are deliberately crippled to create the market for 50 different bundled and third party file sharing apps and other reinvented wheels, with data and money trickling to the platform owner. In addition, rat race never ends, and the developers must update their apps constantly. Say, there is some ancient BTSync installer for Windows. It's rough, but it works. I'm not saying anyone should use that, but you can still transfer files that way. Can you use smartphone apps from ages ago in the same manner? Most likely not (and race organizers make sure you can't). It's quite like constantly resetting the MMORPG server to restart the money and activity flow into its economy.
