On the other hand, if I need a replacement part for something, it's unlikely I will find the manufacturer giving me models for it. And if a manufacturer is giving me models for it, they probably do so with the explicit expectation that I might end up using them to manufacture a replacement.
In most cases either me or some other volunteer will need to measure the existing part, write down all the critical measurements, and then design a new part from scratch in CAD.
Even if somehow you are able to fingerprint on those critical measurements, that's just _one_ part.
The only way this kind of nonsense law could work is if you mandate that 3D printers must not accept commands from an untrusted source (signature verification) and then you must have software which uses a database to check for such critical measurements, ideally _before_ slicing.
Except that still doesn't work because I can always post-process a part to fit.
And it doesn't work even more because the software will need to contain a signing key. Unless the signing key is on a remote server somewhere to which you must send your model for validation.
This is never going to work, or scale.
There are even more hurdles... I can design and build a 3D printer from scratch and manufacture it using non-CNC machined parts at home. A working, high quality 3D printer.
Where are you going to force me to put the locks? Are you going to require me to show my ID when buying stepper motors and stepper motor drivers?
What about other kinds of manufacturing (that these laws, at least the Washington State ones, also cover)?
Will you ban old hardware?
What about a milling machine? Are you going to ban non-CNC mills?
These are the most ignorant laws made by the most ignorant people. The easiest way to ban people from manufacturing their own guns is to ban manufacture of your own guns. But again, this is a complete non-issue in the US where you can probably get a gun illegally more easily than you can 3D print something half as reliable.
Pretty sure those 50 thousand or so civilians killed on the street in the recent Iranian protests/riots would have been a lot less, if all those Iranians had easy access to guns, and not just the government.
Drones are not enough, you still need boots on the ground for you to claim control over a territory, and boots on the ground think twice about signing up for service if that includes facing armed mobs with guns on a daily basis.
So no, mobs with guns are not obsolete.
So, if one sees the whole of IRGC plus Basij as the "commandos", they alone form an active elite of about 0.5%, if one sees the entirety of the military+police we're looking at easily 2-3 million units, so up to 2%.

Drones cut both ways. You’re correct that it allows a small number of people loyal to the regime to asymmetrically oppress a large population. But drone technology is in theory accessible to the populace in an industrialized country.
The Taliban are a military and political group compromised of an ethnic minority in Afghanistan. It's not even that the US lost to "goat herders with guns". We failed to secure a small country against a well organized, armed minority.
2) The weapons culture of the US is so obsolete that there are government officials parroting lines about it not being legal to carry a concealed weapon during a protest in Minnesota when it is, actually, very much legal. That is to say, it's not obsolete at all. Given the prior public stances of the Trump administration on firearms, this is incredibly telling, and all the more reason why you can't trust people like them.
On the flip side in any domestic insurrection, the soldiers know the terrain, language, customs and culture of the people, the supply lines are nothing (rather than having to airlift materiel and people thousands of miles, you drive them on regular roads), the infrastructure supports espionage, most people support the regime and will collaborate to return to stability (since they voted for it), the regime never leaves (you can leave Afghanistan, you can't leave your own country or it ceases to be a country), and if you lose, you lose territory and/or politicians run the risk of violence. The stakes are why these comparisons are never relevant.
Then the americans tried. They were not goat herders. They failed.
The pattern is clear.
Neither does DRM, really, but it certainly causes a great deal of inconvenience, and is upheld by the legal system.
If you were paying any attention at all, you'd see pretty much every 2A community, advocate and lobbying group was outraged by that statement and made statements against it.
Having said that, it is actually illegal to carry a firearm to go commit crimes like destroying government property, assaulting federal officers and obstructing them in carrying out their constitutional duties.
