OMG . Not personal, but you're delusional and/or straight up lying. Denser cities are more enjoyable to live ? Wrong. Denser cities safer for children to play outside ? Wrong. Cities are loud because of cars ? With all that increased density you will have your surroundings much noisier when it hurts most - at the end of the day, when everyone is back from the job, and having a good time at home. Loud music, celebrations, brawls, arguments, etc. No, cramping more people in the same space will not this space more livable; ask Chinese .
