I think there are other options regarding security, such as detection rather than prevention, and I unless all inter-component communication is encrypted then ultimately it still can't guarantee security (or even then, although this is all varying degrees of unlikely, at least at the moment) Really the crux of this is whether this is best answered by the markets like you say, or by regulation. I see plenty of issues with it being answered by governments, but I have absolutely no faith in the market coming up with a good solution for this, as the players have too much power and the consumers are uneducated. I worry, of course, that governments will stick their oar in but paddle in the opposite direction.
