You're not looking at this as part of a comprehensive policy. If you bypass normal remittances, you out of the frying pan and into the fire of processes that make your illegal status visible to the federal government through KYC and all the "soft" rules that are in place that track people that use gift cards, etc. If someone had the political will, it would be trivially easy to identify practically all illegal immigrants who operate in the country and use any mechanism to store or transfer money. You don't even have to be more "evil." The processes and information are all already in place. Just a man willing to use them would have to be placed into a position of power. Even if you're legal, as soon as you bypassed the remittances law you probably committing half a dozen other crimes, that are easily tracked. Regardless if this is a "good idea" or not, it is very, very feasible.
