You have described the lawmaking process of basically any country. We can't actually write laws to solve real problems because real problems are hard and you can actually tell whether they've been solved or not, but we can write laws to solve imaginary problems and then when nothing changes declare victory.
You can pretty much tell when any given administration has run out of ideas once they start making a huge amount of noise about laws that affect to first and second order literally nobody. 3-D printed guns is basically California's version of illegal immigrants voting in elections. Both things happen to a vanishingly small degree that it's not worth taking any action on either, but you can make them sound like they're the greatest threat to America if you have a megaphone loud enough.
I’ve observed this behavior, but never came up with such a succinct (perhaps pithy) way of describing it.

Eh, small thing there. Ever notice how when discussion about voter ID laws in the US come up that commenters from other countries are absolutely blown away by the idea of not having to show an ID when you vote? Because it’s such an obvious thing to not just leave up to the honor system, like we do? Point being, everyone else seems to think this “thing that could never happen” is worth safeguarding against.

Not making excuses for politicians, but nearly all big bureaucracies start exhibiting this same behavior. It is the lamp post fallacies of problem solving.
