This one of the most ridiculous, knee-jerk reactions to new
technology I have ever heard of.
He must have never heard of "zip guns," that any punk on the
street can build from less than a dollar's worth of parts
without needing a $3000+ 3D printer, knowledge of 3D modeling,
and the principals of gun smithy.
I suppose he will want background checks and registration for
buying PVC plumbing parts and potatoes least someone fashion a
potato gun.
At the time of the American Revolution, authors, publishers, and
printers were regularly imprisoned for seditious speech. The
framers of our constitution apparently felt so strongly about
freedom of expression and the press that it became the subject of
the First Amendment of the United States Constitution.
If every "disruptive" technology were so highly regulated we
would not have cameras, phonographs, radio, television, audio
recording, photocopiers, VCRs, personal computers, let alone the
Internet itself.
