The crafters of the act already decided it's important for the public to know what a person owns, and it leaves it up to the commissioner to make a decision as to what to do with those things. Most of the things they own that are of consequence are either disposed of or placed in a blind trust. It's only items that are below a minimum threshold that people can hold.
It seems to me that the legislature took this decision to say that we want to respect the privacy of people and we want to encourage people to come, and therefore they don't have to disclose everything they own and how much. They have to deal with it in such a way that there's no conflict of interest, and that's a choice the legislature took.
