Spencer: free to drop connection with the State

"If every man has freedom to do all that he wills, provided he infringes not the equal freedom of any other man, then he is free to drop connection with the State--to relinquish its protection, and to refuse paying toward its support. It is self-evident that in so behaving he in no way trenches upon the liberty of others; for his position is a passive one; and whilst passive he cannot become an aggressor."

--Herbert Spencer, Social Statics
