I agree this is interesting, but the problem is that there is nothing to stop the government of the country in which you physically reside from having different ideas about what laws govern your dealings.
If the country you are physically in wants to (e.g.) tax you, they can. (There are, of course, many more nefarious possibilities than taxation.) This is, I think, true in an "in accordance with international law" sense (though there is the possibility that a bilateral double taxation treaty might apply) and it is certainly true in a "who's to stop them" sense. (And if we're hypothesizing that the person is physically located in a corrupt/war torn country, the latter would probably be all that matters anyway.)
Can they though? If all of the money is kept in Estonia for example, and none actually goes through your identity or a business elsewhere - then that company wouldn't have any right to it from my understanding. Until you pay someone in another country - then the other one can't dip their hand in it. Isn't this why so many companies are based out of random countries to begin with?
It's hard to spend money that is hidden from local tax offices. Local authorities can even blame you if your lifestyle is higher than your declared income.
