> whether the government should be able to prohibit technology

There is no principle that says governments (as representatives of the people) can't regulate what technologies people can have. Sometimes we decide that yes, the government should do this. Consider how the FCC regulates electronic devices to prevent radio interference. Enforcement is lax and as a hobbyist you aren't likely to get caught, but devices aren't commonly found in retail stores that don't have FCC approval.

There are many practical issues, of course, including making sure there is a balance of power and that law enforcement powers aren't abused. I agree with that part.
