They're not different unrelated corporations, they're subsidiaries of a parent that is ultimately a US entity.

The citizen has literally upped and moved themselves entirely to a foreign country.

The corporation has just forked a bit of itself elsewhere.

And yet the corporation can't be taxed, but the individual can.

It's not just forking "...a bit of itself elsewhere..." -- corporations in different jurisdictions are taxed differently. That's the whole thing.

The relationship between companies can be a complex matter. Do they have to be wholly owned subsidiaries, really?

You still haven't answered the question: What are you going to do when Apple or Google becomes "subsidiaries of a parent that is ultimately not a US entity"? What about your proposal prevents them from registering the parent company somewhere else while changing nothing else about their operations? Making them file different paperwork doesn't accomplish anything.

would in this case help to treat Apple and Google as foreign company? No government contracts (or super strict rules to get them), tariffs…?
