It is incredibly ironic that the very people that claim the system is bad, effectively cannot survive on their non-conformist lifestyle without the current system. In a way though, it's no different than a religion. Priests cannot effectively survive without parishioners giving them money. Priests likewise preach things about the modern era of morality are bad and we must change them. So if you think of these vagabonds as "roving priests" then what they are doing is of the same concept. Although the difference between a local priest and some modern hippie rhetoric is a priest has relationships with his congregants. The idealist vagabond does not. So it's much harder for them to garner any support.
