The one thing I dislike is the chewing gum part.

Sure, if you litter with it, get punishment. But just for chewing gum, or using a vape (not like in a crowded area but separate from people where you don't annoy others)?

On the other hand, enforcing social norms this way does make the city more liveable. In the western world, social norms have collapsed these past few years to the point where everyone selfishly can do whatever they want, as acceptable behaviours haven't been codified.
