It provides documentary evidence of financial transactions and hence be able to identify the audit trail of a particular transactions so as to obtain more meaningful information. Sketchy accounting information is thus better than none.
As rightly observed by Brian, the justification could be:
a) It is statutory
b) It helps in improving quality of documentation,
c) It helps in taking corrective action in case the financial health of the organization is not good.
It could be that such information will be useful for internal decision making which may not make any meaning to external users hence the information may lack the content that external users will be looking for. One can not really say that accounting information lacks information content because it will depend on the category which the individual or institution falls; probably the information content did not meet the expectation of the individual but it doesn't mean it may not have met the expectations of others because the statement is prepared using standards that are prescribe by law. This is one of the limitation of financial reporting as it may not be able to meet the expectation of all concern.
