Do we even need to bring up not worshiping or serving idols??
IF the Ten Commandments (the law) are no longer in effect , what is the problem with 'worshiping or serving idols'?
It's never stopped you before; why not? Not that your argument is even legitimate.
Actually, it's the bowing down to graven images where they are breaking the command.
Now, they can get into all kinds of semantics about what *worship* is, but bowing down is pretty objectively observed.
And the command is to not BOW DOWN to them.
