Every country on earth has export reporting and foreign currency exchange laws. Between the two, there is always monitoring (for large transactions) and regulation (tariffs, duty) of international trade and capital flows. Keep in mind it was illegal in the USA to actually export crypto source code for keys of a particular strength in the 1990s - it was viewed as a "munition". This is why web browsers had 40-bit and 128-bit SSL versions. Those were lifted eventually due to efforts from the software/web business lobby. However, it still is also illegal to export many classes of goods and services to particular nation states that are undergoing US sanctions. if your homeland is Iran or Syria, for example, you're not going to be sending dog biscuits. If it were Pakistan, you probably could - but it would have to be reported as part of the export manifest with FedEx or DHL. Same goes for electronic transactions like bitcoin.
