Actually, no. With the high availability of PCB's and the upcoming ubiquity of 3D printers, the reality is that such overreaching restrictions as you propose would do nothing but slightly push the market back toward the realm of hobbyists. Let's look at laser pointers--a good example since those with the strength to affect aircraft became commercially viable in the early-mid 2000's. They're affordable, and have a similar enthusiast following... and yet the incidences of lasers being pointed at aircraft per anum is surprisingly low, seeing as almost everyone gets caught, and the punishments are severe. Trying to regulate technology in the manner you suggest would just incite people like me to be more interested in building and producing that which is unreasonably restricted--affecting public perception is far more reliable in terms of generalized safety from idiots and reckless negligence.
