Sure.

But the people with the skill-set and interest in doing that are going to do so anyways; I don't see how anti-theft tech would convince that type of person to shell out an extra few hundred for a bike. They would just buy something and install it themselves.

I just don't see the market for integrated anti-theft. Seems more like a custom component type of thing.

I'd go further than that -- riding a cheap bike with a heavy U lock makes theft so rare in most places that it's not worth wasting any further time/money on the problem.
