No, it can potentially complete its potential in development. Your assignation of right is arbitrary (as is any). It isn't like sperm or your blood, which isolated have reached theirs. The unborn, from conception, are more than that. The rest is argument and the laying of subjective valuation. So you can believe that being less than the fruition of potential lessens and that's your right, but it isn't an objective truth.
As a compact, we have set the idea of right and its vestment, the inability of our compact to alienate right absent actions outside the possible in our consideration. Within the recognition that we cannot demonstrate a necessary point of vestment and the principle that the point exists lies the argument against abortion.
