I believe many of the ideas noted in the article are noble, but in practice, unmanageable. Like Communism, it appears to be utopian in nature, but when somebody becomes greedy or doesn't pull their own weight, it ruins it for everybody else. And, like many arguments presented, we shouldn't NEED guns for protection, we shouldn't NEED to worry about break-ins, but we don't live in the essence of perfection here. Hence the reason for Law Enforcement. I live in Seattle, Washington, and, if the police department is anything like the fire department, you may as well count yourself a sitting duck. It literally takes 10min to get here and I am in visual distance of the station.
A friend of mine has an opposing view, he feels police protection is more than adequate. Though, he has not lived like many urban dwellers have, growing up in a rich white bread section of town. I don't want to call him an idiot for some of the arguments he presents, but the idea sure comes to mind over and over again.
A gun is a gun and just because one looks "evil" doesn't mean it is any more lethal than the one before it. Much like a lifted Chevy Suburban in downtown NYC, who is to say your ride is any less feasible than a Geo metro, excuse me, but aren't you the one to make that determination and not some bureaucrat.
My two cents
