For those people it's a matter of buying a number of chargers that they can choose between.
They can limit access to those chargers to the people living in the building or allow anyone to use them and make some money by selling the electricity. You can even have access control depending on the time of day.
Another benefit is that you get load balancing when many people are charging at the same time.
Private chargers are only a good idea if you there's only a few living spaces.
