1) Weak leadership
2) Lack of material (economic, political, military) incentives, rather than LARP incentives (status and norm).
3) Lack of any plan other than mutually reinforcing gossip and fantasizing.
4) Tendency of weak members to fantasize and emote, and degrade the conversation
5) As such tendency to attract larpers not activists.

People act on (expend energies for) material opportunity.
Not LARPing.
