So following your logic, if I were to buy a big plot of land and develop it with the intention that kids can play there, and then I decide to leave the project behind and gift the land to the community. And suddenly, years later, after all the kids are happily playing there, some junkies show up and start doing heroin, smoking crack, etc. there. Then the community should just say "it is what it is" because it is a public good. Even though it was intentionally designed as a playground for the children, we should not even try to get rid of the bullies.
