So why not register those firearms, so there is a way to trace a

that infringe anyone's rights?

It clearly infringes the right to be let alone. Of what actual
beneficial use is the registration you describe? At the point the
authorities knew of the firearm, they would confiscated the weapon after
its illegal use. Once confiscated, it's no longer in circulation. At
that point, what good would it be to harass the former legal owner?
Answer: none.
