Why do Asian cities choose to plant trees with the smelliest fruit in the world?

I was sitting in this café for about 10 minutes thinking “Man, it smells like someone puked in here” before in a flash of inspiration I looked at the bottom of my shoe and found the squashed gingko fruits that were responsible. In Tokyo, Seoul and most other Japanese and Korean cities the smell can really ruin a walk in the park at the wrong time of year. What exactly are the benefits of these trees that make that reek worthwhile?? Pretty yellow leaves in autumn?? Small leaves so the trees don’t need hacking half to death to stop falling leaves from inconveniencing people?? Anyone got any other ideas??
