Our local surroundings could be made into a dense volume of self-replicating computronium hosting as many bare-minimum sapients as possible, but only a few people here would argue that it’s morally imperative to carry that out to full term.
Another difference is that the mature sapient has typically specified, or would specify, that it should be reinstated in advance, and works within the framework of society. If the baby survives any sort of abuse it undergoes until it is sapient, then it might be entitled to some damages, but until then, it lacks self-ownership and is susceptible to destruction by its possessors.
