100%. It would strongly behoove the US to encourage domestic 3d printer manufacture (or friendly countries like Japan), to the point of bannning Bambu and Chinese companies. Obviously we are doing fine for industrial 3d printers, but the small scale consumer stuff is very important too.
If and when AI commiditizes professional services, it would be good to have modern industry to fall back on. With 3d printing the gap isnt insurmountable yet.
However, our country is run by lawyers, not engineers, so I dont have too much hope. At least a lot of our billionaires started out as engineers...
The cost of your proposed policies to consumers, to the Americans who can create because of cheap great Chinese printers and wouldn't be able to create under your policy... is much greater than the abstract industrial policy benefit.
