It does, in fact, exist. The experience of ephemerality is all that's necessary, and the experience is that you take a photo, it exists for 10 seconds for all intents and purposes users care about, and then disappears.

Their target market is 2% people like you (nerds concerned about privacy and indirect/intangible principles) and 98% people who just want the experience.
