Out with the old in with the new?

This concept of out with the old in with the new is further discussed in "Revising copyright law for the information age." While Litman's examples more directly relate to a time in copyright history that is closer the present, her assessment of the pros and cons to using vs ignoring previous copyright example puts the debate surrounding copyright into a more presentable context. Should we operate on an older model or should we create a newer and more modern system that can better handle the demands of digital enterprises and the ideas created within this environment? The question then becomes how do we go about making these changes, if any? Should the laws be more manageable to the average person (179)? Without this adjustment in presentation to the lay person versus copyright lawyers, is it even worth it to make the necessary adjustments that will bring the law more in sync with digital influence?
