If they protested lawfully from the sidewalk then they could be heard by everyone passing. Even "peaceful" protestors want to unlawfully block roadways, which forces people to stay in their vehicles and listen. There should be freedom for everyone, restraining vehicular traffic from leaving is not allowing that freedom.
Ours have actually been heard saying they're mad that police are blocking traffic because that doesn't allow them to block traffic.
It also protects the protestors because people get pretty angry and drive through protestors when they block roads, so blocking off roads from outsiders allows them safety during their display of their 1st Amendment.
