Let me turn that question around: Why would you believe that multiple
imputation is impossible if you did not do the collection yourself?
The data is the data regardless who collected it. Now it may be that
those who collect the data know a lot about the data, and that helps.
It may even be that they know things about the data, that for privacy
reasons they cannot share with anyone else, but can use in an
imputation model. But all that does not make it impossible to do
multiple imputation on data you have not collected yourself.
