I think having no parking spaces actually makes sense for blocks in the inner city when having a car is really an unnecessary expense.
I lived in a block with no onsite parking (and no parking permits available for residents) in Chippendale for the eight years without any problems. Granted it may not be for everyone, but I took public transport most places and borrowed the car of a family member for those occaisions where public transport was not possible. I also found there was no real need for a visitor's space either as there was plenty of on street parking available evenings and weekends.
Last year, however, I got a dog, which necessitated the purchase of a car and a local car space because (unlike most civilised countries) I cannot take him on public transport.
