No one is worshipping it. Show me a picture of someone praying in front of it or leaving food for it. That's what people did/do with idols. The point of the second commandment is simply this : the map is not the territory.
Things that you think are real are not real, or at least not completely real. If you think they are, then everything around you is an idol. You're not inhabiting the real world - you're in your own mental model of the world, and that's only a map. A perfect map wouldn't be a map, it would just be the territory. Where is the map? Inside you. If you know its not the real world, then its only in your head ; but if you mistake **_things_** with reality, then the image of the things is engraved on your heart, and "you" are in the shape of the image. This is why Jesus says you're saved if you **_believe_** - believe what? Belief in Christ precludes a belief in the material world. You can't serve two masters. You can't go down both roads. Are you seeing what I'm saying? I feel like you could read or hear these words and not get it.
Statues can be idols, yes. But if you're so confused that you think a thing is a god, then you would have to already be confused about the entire experience of reality. To an idolater, a stapler is an idol, even if they don't know it. When you're hungry, for at least that moment food is your idol. When you're horny, for that moment sex is an idol. Your character, your behavior, your thoughts are all in the shape of the idol. The idol is "graven" because you are graven. You can have statues without it being idolatry.
