I get kinda the theory behind it but I think you've hit the nail on the head.
"Come build a factory in the US, we'll make it financially good for you, and our power means you will always be able to export" makes sense - especially as we're over reliant on Taiwan for semiconductors.
But this feels mad.
If I were the EU/UK I would be going, offering the same deal but promising free trade with markets in china/brazil and india so you can make the chips cheaply and export easily.... It might cost the host country a bit, and not raise much in taxes, but you'ld gain the semiconductor manufacturing capabilities....
