This Article greatly benefited from the comments and criticisms of participants in those conferences, as well as from those of Larry Alexander, Shyamkrishna Balganesh, Oren Bracha, Ben Depoorter, Kristelia GarcÃa, Jane Ginsburg, Brad Greenberg, Paul Heald, Justin Hughes, Roberta Kwall, Orly Lobel, Glynn Lunney, David McGowan, Joseph Miller, Justine Pila, Lisa Ramsey, Terrence Ross, Guy Rub, Matthew Sag, Pam Samuelson, Maimon Schwarzschild, Ted Sichelman, Steve Smith, Horacio Spector, Christian Turner, Chris Wonnell, and Christopher Yoo; and from excellent research assistance from Ananth Padmanabhan. We are especially grateful to Wendy Gordon for critical comments and constructive suggestions and for encouraging us to carefully rethink our original positions.
