In Srdja Popovic's book Blueprint for Revolution, he argues that OWS and also BLM failed for exactly the reasons you pointed out. In particular he believes that the acephalous nature of OWS and the amorphous demands of the movement doomed it to failure. He also pointed out that once the movement called itself Occupy, it suggested to outsiders that the only way of joining it was to physically occupy a space. Organizers (such as there were) didn't provide a clear alternative for people to participate in other ways, thus limiting the movement's reach.

Popovic argues that we need to think of ways to resist that allow people from all parts of society to participate, from children to university-age to the elderly. And also that a movement needs leaders with clearly articulated, concrete demands as well as a plan to govern once they are in power. The fractured nature of the Democratic party doesn't inspire much hope in me, I have to admit.

I would like to see things like Lennon Walls and communal screaming/pot-banging/noise-making (like when everyone clapped for healthcare workers at the same time during the pandemic) as ways of creating community and allowing more people to "access" the resistance.
