> Laws are not beliefs they are societal contracts.

Societal contracts are just collective beliefs. When the number of people upholding a particular societal contract goes to zero it ceases to exist. Just as any other belief, it requires believers to exist. Unlike, for example, the space rock that some group of sentient organisms decided to call Mars.

it is not about "believing a societal contract". It is about believing that other people follow it or not. Contract is not a belief.
