 You've made the sidewalk look nicer. You've also made it so that, practically speaking, the homeless can't set up their encampments anymore. And it worked. The homeless encampment was dispersed. The sidewalk was walkable again. Businesses started getting business again. The community had been improved. It was safer. It was cleaner. Everything was great. A community came together, solved the problem, solved it efficiently, cheaply, and nobody got hurt.
