This sounds great in a utopia where everybody is quiet and considerate, delivery drivers don't throw boxes and crates around, people don't get drunk and smash bottles in the street or have arguments. Having lived next to and above commercial properties I can say it doesn't improve quality of life, it drastically impacts mental health, stress, and sleep. There's a reason that we have commercial districts and residential districts.
