There is tremendous amount of economic damage. It's literally using force and violence to not allow people to use what their tax money paid for. By blocking street you can create zones that are lawless because no 1st responders can get in. As we saw with the riots and looting. Blocking streets and freeways to be considered domestic terrorism immediately and have all these people arrested. It is not peaceful protesting if you want to stand on the island and peacefully protest do that the moment you're blocking traffic your a domestic terrorist.
