From the paper, “This paper aims, in the first place, to put a concrete proposal on the table. It is not a panacea; it is a plausible way forward. We will start by explaining our proposal in detail and the problems we believe it would solve. We then discuss the proposal’s strategic rationale at a higher level, how it compares to various past and current practices, and why concerns about the dangers are considerably exaggerated. We conclude by considering the specific legal changes the proposal would require.”
