You've upset people because what you seem to be talking about is either highly specific prohibitions, or a general prohibition on unlicensed tinkering and innovation. The latter will go down like a ton of bricks here and would have prevented most of the computer technological developments of our lifetimes.

But the way out of this is actually to make the constraint more orientated on the harm. Several jurisdictions already ban the sale of spy devices. Many have rules about non-consensual recording. Or general privacy rules.

Don't try to ban buidling things unless the other approaches have been tried and failed. The solution to "upskirting" and other non-consensual intrusive photography has been bans on doing that, not a ban on smartphones. There are all sorts of things that you can legally build and tinker with but not market to the public.

(Security researchers are particularly salty about this because you can't get people to take a threat seriously without building a proof-of-concept, but that is in itself a weapon. Often you can't prove a system is insecure without breaking it.)

I don’t know how to reply without being too snarky. Is your position that we shouldn’t “allow” someone to build a wifi module hidden in a USB cable, because we don’t allow rape and murder?

I’ll let someone else see if they can help you out. But I think you need to take a BIG step back and ask yourself this “have I solved all the problems in my own life” and if the answer is no, stop thinking so much about what other people should be “allowed” to do. Worry about self. Take up the position that my right to swing my fiat ends at your nose.
