Who will be building, and manning all that newly developed industrial base? You cannot create enough labour in 18 months, it's a very hard fact of reality.
Your labour market has been running at full employment for a while, 4-5% unemployment, there's no leftover hands to help with building up multiple industrial bases. Unless you want massive inflation when all these openings for the rebuilding of USA's industrial base, and need to pay a lot to absorb as much labour as possible to actually happen.
Not even considering in how much risk the investors of this new industrial base will be having to hedge against, who knows when Trump will increase tariffs on their inputs until everything rebuilds internally, financial hedging, oversupplying their warehouses to prepare for shocks, etc. are all quite expensive. Who will pay for it?
