I don't think Plato's critique there is necessarily getting at what you're intending. Plato is arguing that direct commands by a ruler are superior to written statute laws, because they allow for the use of good judgment and have less scope for bureaucratic idiocy and corruption than a lengthy statute book does. He's not against the state imposing restrictions on anyone, he just thinks it should be done by direct command of wise philosopher-kings, rather than by codified law.
His system if anything quite strongly restricted what people could do in the economic sphere. The "producers" were one of the three classes kept strictly separate (the other two being warriors and rulers), and must follow the directions of the rulers, as enforced by the warriors, in order to ensure that production is in keeping with the needs and morals of the polis.
