If you think radio jamming should be legal, your issue isn't with the FCC, it's with US law, specifically 47 U.S.C. 333. Complain to Congress.
Despite that these and other jammers would have some beneficial uses, in my opinion it's a very good thing that radio jamming is illegal (with some exceptions for law enforcement and national security). Legalizing radio jamming in any form would cause far more problems than it would solve.
