I think you are equating those with disruptive. Peaceful doesn’t necessarily mean non-disruptive. Peaceful and disruptive protests can certainly still make people in power sweat
Strikes are peaceful and disruptive
Shutting down freeways can be peaceful and disruptive
Boycotts are peaceful and can be disruptive
Sit-ins are peaceful and can be disruptive
etc.
Not that 3.5% is necessarily an iron-clad guarantee

EDIT: also organizers within 50501 estimate at >11 million (50501 is one of the groups involved in the No Kings protests) https://bsky.app/profile/50501movement.bsky.social/post/3lrmozcmqx223
