Don’t worry. it belongs to a completely different authoritarian government now.

That’s why I phrased it the way I did, “resulting repairs”. No amount of maintenance will prevent anything from breaking. But no maintenance greatly increases the likelihood of something failing because of that neglect.

That’s deep.

True. But even more (expensive) things break on unmaintained vehicles.

Unpopular opinion: Maintenance is far cheaper than the resulting repairs.

I think they are responding to the OP’s comment:

and would also potentially be somewhere between a misdemeanor and a felony depending on where you are in the US, as 3d printed firearms are generally without serial numbers and are thus ‘ghost guns’, which are often illegal if unregistered, if not outright banned, though this differs from state to state and city to city.

Which has nothing to do with NZ.

Edit: that last bit sounded catty; not my intention.

However, selling them without a serial number is illegal.

That’s not correct either . Federally it is legal to sell a self built firearm with no serial number as long as you did not originally build it with the intention of selling.
