In theory you are right but the reality of these dancing grannies is that they can be loud as hell. Like, disturbingly loud over a huge area and the noise pollution they introduce can be bad even by China's fairly noisy urban environments. Public spaces get tons of use without them, anyway. Also, sometimes they are fine and completely benign. It's the ones that become a local "thing" and draw huge crowds as well as that have no consideration for the surrounding residences that are a problem. I love the sounds of daily life in China (even the occasional new business opening fireworks extravaganza at 7am, lol) but the noisiest of these dancing granny groups are really a bit much.
