Money is inherently interconnected with government. It is the government that issues money. It is government that demand that taxes is paid using their money. It is government that issue regulations for finance, and it is government that enforce laws that protect money and the processes around money. It is governments that generally insures banks.

I am perfectly fine with banks being exempted from first amendment rules if the bank has no relation with governments and when the government do not depend on banks to operate the financial system within the nation. Otherwise the bank is just an extension of the government, indistinguishable from a government department.
