There are no papers to be destroyed. Your associated content source is only talking about a relatively recent lists of renunciations. Besides, there’s still no evidence Obama ever had U.S. citizenship to renounce prior to becoming an Indonesian citizen.
The U.S. State Department has no record of the annual number of Americans who do renounce their citizenship. However, the IRS publishes their names in the Federal Register. The IRS’s interest on the subject is a financial one; since 1996, the agency has tracked American expatriates to try to recoup tax revenue, which, in some cases may be owed for up to ten years when a person leaves the country. In any case, the actual number of people renouncing their citizenship, for example, in 2002 the Federal Register recorded only 403, of which many were merely longtime resident aliens who were returning home.

We still have the school record from Indonesia and NO DOCUMENT from Obama to dispute it.
