Swinging to the other side, would you really want to allow an alphabet soup agency to make a virus or nanotech (a literal "bug") to infiltrate your body and monitor everything going on with you on the off chance that some nutjob does the same thing?
Honestly? Yes. Already some way to artificially boost the immune system would be a good thing, and in a world with advanced nano/biotech available this seems like a no-brainer. We need some sort of blanket protection not only from potential attackers, but from much more likely accidents.
