Completely agree that the presence of bikes and scooters on the sidewalk is annoying and dangerous. The city changed the rules a few months ago and now there is a 500€ fine if you use them on the sidewalk. That fixed the problem. They have to use the street or one of the many bike lanes.
No idea how it is in Paris, but there are places where living happily in a city without owning a car is perfectly possible, even if you have small kids.
You should stop and have coffee in a street shared only by pedestrians and cyclists, and observe the behaviour of cyclists. I have observed it to be mostly slow, controlled, courteous and respectful of pedestrians.
No, I don't feel safe at all, and my son can't walk freely either. In Paris it's the same (my wife, who was pregnant then, got hit at a crosswalk by a cyclist who seemed to believe that red lights were for cars only). Even Le Monde published an piece about it!

Look at rent in Asia. They actually build towers over there and they build large apartments for families as well as small apartments for couples. There's enough building that the housing market is diverse.
