It wasn't even a ban though. It was a restriction on the size of the container. You could still drink soda, as much as you like. It's well known that when you put larger amounts of food and drink in front of people, they consume more, regardless of whether they felt a physical need for it or not. Instead of letting marketers use psychological tricks to make themselves more money, I'd much rather let the government use the same tricks to make the public more healthy.

Even if science later finds out that soda is super healthy and we should all drink nothing else, I'd much rather have regulations motivated by people asking "Is this healthy?" instead of "Does this make me the most profit?"
