An idea from someone else, that there should be a rebel license and also rebel training, so the training should cost $500,000 and isn't lost in goin to jail, but the license should maybe be $100,000-$250,000, so it still costs to be a actual rebel but you won't have to fork out half a mil every time, so it will deter a lot more RDMers as it will cost even more to have access to rebel gear, but for someone willing to do it properly it won't be impossible.
And may also stop rebels killing police on sight as they know it won't cost too much to replace .
