I also assume you don't live in a dense city. Even in a utopia you couldn't have perfect safety without investing in security: some people are going to commit crimes and violate property just for fun, and when there's a lot of people in one area, that becomes a concern.
There has never in history been a time when people can be secure without investing in security. To claim that investing in security is in indication of something "wrong" is therefore at best a sentiment far ahead of its time.
