Your analogy doesn’t work, because the general consensus is that there is no better alternative to taxation. It is a necessary evil - unlike Stallman, who, regardless of personal opinion, has others who are qualified to replace him.
How are the alternatives safer from the same complaints? I read on the internet that they beat up little old ladies.
That's not how I read your analogy. If the tax situation made him move countries, is that country better off without their contribution? Would resolving the tax situation make that country more desirable to contribute to?
