Producing real things is not just a matter of money. You need know-how and supply chains. These things left the US at least 10 years ago. It can get them back, but the costs will be staggering, and it would need to compete against China and other Asian countries.
Many of those Asian countries are our allies. If you want to argue for weapon or dual use stuff like drones that's one thing but I don't see how making cellphones help. Also we do make real things both physical and non physical
As the last 15 years has shown, being ally only works until US decides to choose themselves first. Even weird comments about Canada’s independence can sway population’s perception. There are genuine conversations about “maybe we shouldn’t have severed our ties with China” on the ground nowadays.
