Not everybody needs to do that, but then you need to rely on people you can trust. Of course we already do that to some extent in app stores: I don't install something from unknown developers that requires all sorts of permissions it shouldn't need, I do install from developers I think I can trust. But if I don't trust them, I lack the ability to inspect their code. That's indeed the big thing that's lacking.
