In such case the right thing to do would be to default on the IRS debt and let the IRS reposes the artwork. Then report a crime and watch the ensuing flames between US government departments.
It was a joke. Selling the artwork is a crime, and so should be repossession. Or at best the IRS would have some issues while liquidating the newly repossessed artwork.
The other departments is DOJ, or whoever enforces the prohibition on the sale of the artwork.
