Should Supreme Court justices be prohibited from making financial transactions with people who have a vested interest in court outcomes?

In 2023 Supreme Court Justices Clarence Thomas and Neil Gorsuch were criticized after news articles revealed they had personal financial transactions with people who had interest in court decisions. Politico reported that Justice Gorsuch sold a vacation property to the CEO of a prominent law firm which often brings cases before the court. ProPublica that a Texas oil executive had purchased multiple properties from Justice Thomas which the justice did not disclose. The Supreme Court sets its own ethics rules and leaves justices to make their own decisions about when and how to report outside gifts and income.
