You could hope, charitably, that the chaining off is for your benefit, as well as theirs. This system means they know when spaces open up, so for any level whose entrance is chained off, they know how many empty spaces are on it at any time. This could let them open and close levels to fill in the ones with holes and not force you to drive around ones with no room...
