because it would be counter productive. An individual rebel would be craftily demonized and labeled Terrorist, so any lonewolf effort would be counterproductive and entirely innefective.
However,a force of about 25 militia armed like the "North Hollywood shooters" could get the attention of congress and the executive branch by completly eliminating them from existence with extreme predjudice, but they would still be dubbed "evil terrorists"
it would take a large well rooted and and well understood organization with clearly defined goals and established doctrine and a system plan to replace the corrupted government to have any positive effect at all. All else would be more destructive than helpful. It could probably only be done at this point with at least one branch of the military fully joining in.
with out a plan to replace the corrupted government it would only establish chaos to be filled by more tyranny.
signing petitions, joining impotent organizations and bending the deaf ears of politicians is entirely futile. The only prescription that will purge this virus is extreme violence
