you are quite literally playing with fire and will probably find yourself on the loosing end of any battle you have with them.
The government has UNLIMITED resources if they decide to come after you. You, on the other hand, presumably do not have unlimited resources to fight back.
Finally, don't forget about RICO (Racketeering Influence and Corrupt Organizations). If you create a business to engage in a criminal enterprise or to assist others in engaging in criminal activities, RICO was designed just for you.
