> Can you live without 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).

In some countries Canada for example if you don't take a new residence they will treat your last residence as your residence.

India is the opposite. You can work on a boat get paid in India and owe no taxes.
