I think if there were public seating, we could eat or drink outside much easily.
However, I don't think we really need the public seating bacause I think we will not use them so much anyway. In rainy season, no one would sit outside. In the summer, it is too hot outside and we would get dehydration. In the winter, it is too cold so most people would prefer to rest inside. Also, Tokyo is a big city and always crowded. There is no space for public seating.
