In large organizations it is common to have multiple databases maintained by many different people. When a DS needs some data he/she needs to talk to all these different people, wait for them or their managers to grant access, and join the inconsistent labels. This takes a long time and some people are extremely protective of their (messy anyways) tables, requiring higher ups to straight up demand them to grant access. Having nicely organized data is perfect, but I'd rather fetch the data myself from a pile of messy data instead of dealing with all these organizational nightmare.
