Not really. The judge simply ruled she was bound by precedent that her court did not have sufficient authority to overturn. That's actually a good call, but it has nothing to do with the issue or arguments.
In any case appeals to "common sense" aren't worth squat when that common sense is based on ignorance or inexperience. It's common sense to talk about "the dark side of the Moon" or to think that the next flip of a coin is affected by prior flips.
For 80% of the existence of our species we coexisted with at least one other species that would pass any reasonable philosophical criteria for "person": the Neanderthals. If we were able to use biotechnology to recreate Neanderthals, Jurassic park style, there's no question that if successful the experiment would create people. But would they be legal persons?
It's an important philosophical question because it potentially colors a lot of mundane ethical questions. Do we recognize the rights of others as a kind of tribal convention? Or are we compelled to do so because of something in human nature? If the latter presumably non-human entities would have an equal ethical claim to personhood.
