UK law allows fixed blade carry with a "good reason" as a defence but that's the key word. A chef with a roll of knives on his way to work is a good reason. A sailor carrying a sheath knife is a good reason. A guy out camping is a good reason. Even so cops could totally hold and charge you all the same if they think you're bluffing and you might have to prove it in front of a judge. Fortunately cops exercise common sense and judgement, but good luck with your hypothetical.
UK knife law also requires folding blades to be less than 3 inches. It limits their utility to be used commit assaults and on the consequences of the assault. The reasons for this are obvious.
In the UK, people get a national insurance number at the age of 16 for tracking tax / pension contributions & social security payments. I assume the measure is intended to issue the number at birth for similar reasons.

If states want to ban ghost guns then make the penalties for doing it so severe that it discourages people doing it. And start improving ways that ghost guns can be forensically matched back to the printers that made them so that if someone was suspected of making parts, that it could be proven in court.
