I suspect the questioner is conflating two separate themes here; the first, and superficial, is the opting out of any system of coercion; the second, and underlying, is the issue of what happens when an outlier re-enters that system by interacting with another individual embedded in the given system. The resultant of the second, of course, is that the outlier is now again recaptured by the system, and will be treated by the system as would any 'voluntary' participants.
(This would be an interesting discussion, if it was not couched in such knee-jerk trigger terms. The relations between outliers and the systems that claim monopoly to the necessities of life bear heavily, both upon many of our comrades of the day, and upon our own ability to separate ourselves from the 'system' in any near future.)
