Not even that. I believe it has to do with Ruhezeit (Quiet Time.) It's just that rattling the bottles is noisy, so it is more like curtailing freedom in the name of neighbors' freedom to have their Ruhe.
I don't know Germany but it seems you're suggesting Germany curtails freedom in the name of economic efficiency, but not as much as the US for "national security" and what not.
