I'm interested to understand your theory better but right now the way you've expressed it is hard to make sense of for me.
As I said, it is fueled with ignorance and I’m sure that it is complete bullshit when examined closely but the reason I kind of find it possible is that currently the American companies have a reach that is order of magnitude bigger than the American population and their valuations as well as their profits are based on that. What America is currently doing is dismantling of the world order that made this possible, th…
The US is a huge whopping exception to this strong correlation between the balance of trade and currency strength. US exceptionalism is usually wrong, but in this case, the US dollar being the 'reserve currency' of the world is an incredible boon. The US has been able to sustain a huge trade deficit for decades without sky high inflation (you think it's bad now, it's nothing). In fact, foreign goods keep getting cheaper and the US dollar and services keep getting more valuable. A lot of this is because foreigners are willing to keep their savings invested in dollars (stocks & bonds, including the magnificent 7) rather than selling off their dollars to buy e.g. Chinese goods.
Also note that the tech companies make up a small portion of imports/exports.
But.. If trade restrictions (or security concerns) make it harder for the magnificent 7 to make money abroad, their profits will go down and there could also be an outflow of capital that puts inflationary pressure on the dollar, just because US stocks and bonds are less attractive - the trade deficit increasing would also contribute a bit, but it would be a much smaller effect.
An economy being propped up by foreign capital is not just a US phenomenon, the Asian Financial Crisis of 1997, Turkey 2000, Mexico 1994 - these crashes all were cause by sudden capital outflows. The proximate cause was a short term arbitrage trade, rather than those currencies being in extensive (structural) demand.
This concern is also why China doesn't let foreigners invest directly in Chinese companies. You can only buy weird derivative certificates that trade on a Hong Kong exchange and are subject to tight capital controls if need be.
Things like a domestic tax on imported goods/services (also called tariffs) are unlikely to lower the trade deficit unless there is already an industry domestically to absorb the demand.
