@Allodial, it seems to me that such 'Sale of Checks' laws are just further adhesion contracts with which to ensnare the unsuspecting, converting them to statutory citizens. A check is just a negotiable instrument instructing the bank to transfer funds to another. The Fed already assumes that issuing such a negotiable instrument constitutes 'dealing in Federal Reserve debt securities' and thus obligates one to filing an income tax return and paying taxes on the private credit used. Or could such laws be intended to somehow impact transactions in bitcoin and related digital currencies?
