Survival is not a value. Survival is a prerequisite for a lot of other values, but it's not a value in and of itself.
As many people have difficulty grasping what living in a world without privacy would be like, let me propose a different solution: We'll put everyone into solitary confinement, to ensure everyone's survival, as I do not see the value of freedom of movement trumping survival.
Would you agree with that as well? If not, why not?
Also, you might want to realize that surveillance does not ensure that your set of values gets enforced. It's the values of whoever manages to obtain that power, and whose power as a result of the surveillance might be impossible to challenge. The idea that you could create such a power structure and then guarantee that it's going to be used exclusively to prevent that bio weapon from being built and used is extremely naive. You would instead most likely find yourself alive, living in a world that makes you constantly wish for being dead, but thanks to the surveillance unable to kill yourself.
