How is it related to living in a city? At least in the Bay Area you can walk/cycle pretty much everywhere if your work is close enough to your job. And cycling in suburbs is usually safer/healthier than e.g. in San Francisco.
This depends on location. In my area, the suburbs (designed as they were in the 1950s-1970s) tend to be very pedestrian and cyclist unfriendly places, particularly in those areas with business parks. If you want to get around without a car, then you really need to be in the city.
Your second point, however, is right on. I've always made it a point to find jobs within 10 miles of my home, so the bike commute is reasonable (having briefly done a 40 mile round trip commute, I can say that it took up too much of my time).
