The point I was trying to make is that a company's "headquarters" means nothing other than the place they're incorporated.
That "place of incorporation" is a very fluid thing, as it can be changed very quickly to adapt to changing regulations and optimize for rapid changes in the business ecosystem a company operates in.
And therefore: it doesn't mean much.
What really matters is:
- the company's assets financial and non-financial and what jurisdiction has sway over them.
- the people who control the company and what jurisdiction has sway over them
- the company's customers and what jurisdiction has sway over them
In 2023, the people controlling the company may be very mobile as CP has amply demonstrated, the assets can be very hard to control (damn near impossible if crypto, and still quite hard if cash and cash-like).
Where the headquarter actually is is IMO of precious little importance.
