One view that intrigues me from a libertarian perspective (to the extent that I understand the libertarian perspective as a liberal) is the legal status I saw proposed by David Favre (I think?) in the Sunstein-Nussbaum animal rights anthology. In it, it’s proposed that animals’ property status could be changed (possibly voluntarily by the animal’s master) so that the animal would have equitable title to itself, while the master would retain legal title. As such, masters would legally have a custodial role, and would have a mix of duties and authority resembling that of a trust fund manager managing a fund on behalf of a rich minor before he comes of age. I wonder if this could be a libertarian “middle ground” on animal rights between Francione and complete legal disregard. It could be somewhat like a libertarian view of parental rights over children.
