I look at laws as sort of a program code for society - they define a cost function for unwanted behavior (while the economic system defines a reward function for wanted behavior). From that perspective I have to disagree here - I think GP's suggestion is good - laws should be reviewed from time to time just like legacy code should be reviewed for maintainability reasons (even just so that you keep some people familiar with the code). Every decade is probably too much, but every 20-30 years should be doable without too much cost.

The main problem is creating a process where outdated laws can be removed efficiently - which obviously needs to be done in congress. I think there could be a monetary reward involved - not for the congressmen obviously, but for non-members of the congress who initiate a process that leads to a successful removal.
