What would happen is that, for instance, the building manager would refuse to 'lock off' a lift for the exclusive use of the removalists, extending their time to the owners great expense. There could also be issues with access to the building with similarly expensive results.
OCs have a perfect right to protect common property against the scuffs and scrapes of careless removalists. A bond will make everyone just a bit more careful, in which case it can be returned intact.
BTW, I have just learned that my building used to charge $100 attendance fee for the building manager to supervise removals – but then someone (not me) wrote to the papers and it was quietly shelved.
