I get it. Both things can be true. Unstructured writing can help you develop as a person. It can also teach your own model the 'real raw human train of thoughts' of your personal journey. Personally I love the idea of booting up great-great-grandpa-model that'll have been trained on his 40 years of almost daily journaling. We are not trying to 'remake him' to be clear- we are talking about being have to have an interaction chat with his personality-vibe as it was recorded by his own hand and in his own words.
