Do you really deny that there are probably benefits, given limits to average human condition, to at least some hard legal lines corresponding to continuous realities?
/me shrugs…
I suppose it is useful to have a line, and once you decide to have a line, you do have to draw it somewhere, but I don’t see why viability is a particularly meaningful place to draw it.
Similar arguments are often used to argue in favor of animal rights; some humans don’t have brains that work better than animals’ brains, so if humans with defective or otherwise underdeveloped brains (the profoundly mentally retarded, infants, etc.) have moral status, then so do animals such as chimpanzees and dogs.
