While I am fully opposed to a 3d printer ban (and abhor the efforts of Bambu et al to sneak that in), it is very important to understand why that is not a fair comparison and, if anything, sets a threshold that can be used to argue FOR a ban.
I’ve ranted in detail before so I’ll do the short version this time:
You are not going to make a barrel or springs yourself. And the good news is that you don’t need to. None of that is a controlled/registered part (for the vast majority of guns) and you can literally buy those at a walmart equivalent. And there at least used to be pre-packaged bundles available online for your ghost gun needs.
So that mostly leaves the receiver and fire control unit. I will bet you money that giving a rando off the street 24 hours to figure out how to go to the local communal machine shop and make even a frigging sten and they will fail miserably. Whereas there are videos (fuck vice for how they abused their workers but old-vice has a really good video where they literally made the gun Luigi allegedly used) of people going from 0 to glock in 12 hours of print time and 4-5 hours of filing.
And that is the big difference. How much that matters when you are considering a country where you can buy the same gear that Tier 1 Special Forces use to abduct (admittedly really shitty) world leaders for under a thousand bucks is a HUGE question. But from the “ghost gun” perspective? There is VERY much a big difference between having a CNC and machining a receiver+FCU versus doing the same with an Ender 3.

Why don’t they make firing chambers and barrels out of plastic? Are gun makers stupid?

There actually are some really cool proof of concepts where people have 100% 3d printed a gun. And “potato cannons” are generally a PVC firing chamber and barrel.
For legal purposes: Preface everything after this with a dozen "allegedly"s. A couple years back I went to a really cool event where people had built machine guns out of wood and plastic (FDM). None had any issue with doing well over 100 rounds each. That said, anyone with half a brain cell was literally hiding in a bunker nearby out of terror when the firing was going on. But… yeah.
Like anything, it is about pressure, strength, and geometry. And, as The Troubles in Ireland can attest… you don’t need THAT much skill to make something that will fire… once. Which is why there are so many shed machine guns and rifles with split barrels and completely exploded receivers in The Royal Armouries.
