Although it may not be entirely clear weather governments' control, or people's fulfillment would lead to greater safety, but watching Surviving the Singularity by Paul Budnik, it seems that the diversity, which Bitcoin can bring about to our society, will bring more solutions to various problems that we may face than the governments and centralised way could ever address.

I have always been an advocate of personal freedom, and I like bitcoin a lot. However, imagine the following scenario:

1. Someone pays to scientists to design a "Time Bomb Human Virus" - a biological virus programmed to stay silent for years in human bodies, and activate itself at a particular pre-programmmed date (which technically could be achieved by designining a nanoscale virus shell to put a deadly virus in), and with anti-virus only for the people who had designed it.

2. All the mankind dies, except the group of people who had the antivirus.

How could we prevent this without governments, maybe there are technical ways in which we could prevent people using money for such kind of things? Anyhow, since we are now beginning to control our money, we have to wisen-up and think responsibly about its uses.

Just because we love freedom, doesn't make us bad guys. Any ideas how could bitcoin help us defend ourselves against their misuses?

Edit: And, yes, I thought of something like ClearCoin, just to realize that this (unless it is obligatory and de-anonimizing) wouldn't work for prevention of such misuses.
