San Diego County jumped into California’s sprawling ghost gun fight this week, suing a 3-D printing filament manufacturer it says hocks material for homespun firearms in violation of state law.
Working with the Giffords Law Center, the county counsel sued manufacturer Polymaker, alleging the company made a “strategic business choice” to market and sell 3-D printer filament to Californians for the express purpose of building illegal weapons. The polymer filament is sold in spools that feed into 3-D printers, allowing the devices to form designs created by their owners.



Which makes the law useless. People with nefarious plans don’t need ads. There really are just two possibilities, either it is repressive and overreaching or it is useless.
Ok whatever. I won’t try to argue over the validity of your definition of “useless” since you clearly think it’s absolute.
It is not absolute, you are free to argue in which way it is useful, in practical terms. Have you done so?
Do you think any follower of mentioned channel has difficulties finding functional FDM filaments without ads on the channel? If not, whats the point of the law’s application in this example?
