Today we’re talking about something Im paticlary worrid about
In the US legal system, a distinction is made between contract law and property law.
Contract law is extremely permissive: parties can make contracts about pretty much anything that concerns just those parties.
Example: Michael Jordan notably had a “Love of the Game” clause in his NBA contract that allowed him to play basketball outside of the NBA in the off-season, something usually prohibited in player contracts for fear of injury.
Property law is much more limited, in large part due to the fact that property law affects large undefined swaths of people, often everyone not specifically mentioned in the contract.
