The point being that people have to be sure of the (consumptive) boundaries within which everyone is allowed to move (those boundaries must be clear and sharp), and of the upholding of those boundaries (so they must be feasible and just).
If we do not see that political direction and guidance (is not offered to us) we continue to fight each other as competitors around those (indeterminate) boundaries, and do not cooperate in unison (do not help each other) to respect a boundary together.
