Can you live without residence? Say I'm sailing around the world. My home country could be thousands of miles away, pretty much unreachable in a practical way. Should that still count as my residence?
ding You've just discovered another hidden trick that the ultra-wealthy use to minimize their tax-burdens: in each year, they travel and ensure they do not reside long enough in each country to be considered resident fir tax purposes.
It's not really a trick if you don't use the services, especially healthcare or education system. I'd be all in for nomad tax at something sane like 10% or some trade pact that you can get healthcare and edu for free anywhere in the world (already the case within EU).
