Fully Secure

I suppose it's logical to assume that we can never be fully secure, because there's an 'infinite' amount of security threats. First, infinity is irrational. There's going to inevitably be a cap on the amount of threats people can think up of.

Second, money makes the world go round. The terrorists, and computer geeks who keep hacking into the pentagon, will eventually get hired by the pentagon to stop people just like them. Hackers and terrorists do not get paid well hacking and causing terror for livings. They usually end up imprisoned or dead as a matter of fact. They'd eagerly go to the not dark side for a six-figured paycheck and a nice 401k.

Lastly, how much are people willing to sacrifice in order for security. Complete security would only be possible for a full release of personal freedom. We all know the Benjamin Franklin quote: "those who would sacrifice liberty for security deserve neither". Frankly, since complete security is both unnecessary and impossible, the person will lack both liberty and security whether they deserve it or not.
