That was always such a silly argument, even more so with the rise of cheap and reliable 3D printing. I download, print, and use physical objects every week and don’t know or care what IP issues might exist as long as it works for its purpose. I can’t wait until the day comes when you can download and print a working car at home.
Then I'm surprised. It's much different to the usual situation when even mass made products are either banned or very limited, e.g. unicycles prohibited, e-scooters only up to 20 km/h, e-bikes only up to 25 km/h.
