The goal of primary education isn't to understand any particular thing, it's to provide the intellectual training to understand anything. Someone doesn't need to leave middle school or even high school "understanding physics", but with a base for future understanding. The Bohr model is more than sufficient to help understand chemical reactions.

People seem to be interpreting "lie-to-children" as meaning "[you must] lie[ ]to[ ]children". I don't think there's anyone who thinks that children should be actively deceived into not knowing about quantum mechanics, just that it's OK to use simplified explanations as one step in the process of learning.
