Money is a fungible resource and can fulfil different roles depending on the context in which it is used. It can be exchanged for almost anything and should be treated differently according to the circumstances in which it is used. It can be exchanged food, housing, weapons, medicine, services, hired hands. More conventional examples of property, such as real estate, or a car, have no equally fungible characteristic. When it is used to advance political debate, money becomes inherent to political speech. Therefore, in the context of campaign contributions and expenditures money deserves the protections of the First Amendment.
