I think that "reasonable restrictions" shouldn't always override rights; particularly assembly and protest given the importance to those in terms of keep the Republic. I'd rather take a temporary nuisance hit with protesters in a part at night than excuse government force against the exercise of a right. That's just the way I typically side when it comes to rights.
What they want is for people to pay attention to the world around them. That's why they're engaged in a magnitude protest. The main contention is that there is extreme mixing of State and Corporate entities and interests which have brought an end to free market and installed instead corporate capitalist. In this system the government is employed to selectively promote certain entities above others and also leads to the closing down of competition and economic mobility. And on that front, they have a point.
