Clean this shit up

All you people who think that you are simply expressing yourself artistically when you tag buildings need to think again. Purposefully damaging the property of others costs everybody in this city. Either the city or the property owner has spend time and money cleaning up your shit. That time and money, combined with the time and money put in by the vandal, is the opportunity cost of vandalism. That is time and money that could be used to do something productive for society, but because it is used for a destructive purpose, net social welfare is decreased by you assholes. There are certainly property owners who have no problem with allowing people to tag their property. Feel free to decorate that property. Otherwise, tagging is a selfish pasttime. Respect the rest of the people in your city.
