well yeah; but lets look at where we are now. Nobody is make domestic routers because you CAN'T for structural reasons complete with foreign ones.
There are exactly two ways to make domestic router production happen.
1) Defense production act, go all command economy compel some company with domestic electronics manufacturing plant they are going to produce routers. Good luck because it isnt just you with a PCB layout kit, and you there with the injection molding machine, hop to it. It is also design the thing, get the software (even if it is just Linux), .... Nobody at FCC is up to coordinating product delivery with all those inputs. The outcome will be some disaster of product nobody wants, that hardly works, very likely costs way to much, and will be way to stagnant crippling innovation of anything delivered by the net does not fit todays ipv4/6 and relative bandwidth scenario.
2) Ban stuff people need let some domestic company who is already in the business of building somewhat similar products maybe an enterprise player who could jump into the consumer market, that just has to solve how to replace their sourcing with domestic alternatives. Sure it is still disruptive, but at least has some tiny change of working...
3) Then there is the other don't make domestic production happen alternative, which is what most of Slashdot childless, globalist, America hates really want, that is to do fuck all about supply chain risk and the national security and sovereignty implications, because having some new shiny thing for very cheap that will be next years e-waste to play with is more important to them than America's future. While were at it, the public till can get raided to inject cash into some American chip makers so they can design but not actually make any chips, pat ourselves on the back watch our 401ks grow and pretend we did not just sell out our grandchildren at the same time.
