You dont want to lose any of it in case of violence, otherwise it’s evidence that places you at the scene, and you dont want creep cops to “confiscate” anything for the same reason.
You don’t want to be seen with bulging pockets (or even worse carrying any sort of backpack/fannypack, etc) because that makes you a target for cops. Even worse, they can plant things in bags or wallets.
At the bare minimum, carrying no ID when chaos erupts, means cops might let you go to avoid the work, hunt down other easier-to-arrest protestors or gives you the option to give a fake name, then make a run for it.
