If a “back to roots” movement is needed, it must be because people have abandoned at least some part of the original foundation. They did that for reasons: perhaps abandonment was easy, profitable, what the cool kids were doing, etc.
For a “back to roots” movement to succeed, it has to counter or repel the forces that caused that first abandonment. Something needs more protection than it had in the past, in the way that a cactus’s prickles protect it by repelling animals that would otherwise suck it dry.
