1) A proven set of developmental genes.  A very large number of spontaneous abortions / miscarriages, have a direct cause lying in the faulty genetic material of the egg/embryo/fetus.  Certainly we may expect some technical difficulties producing a viable egg until the medical community perfects cloning techniques, but that question comes down more to issues of when rather than if.  The genetic material of a human gets its greatest workout during prenatal development, so the vast majority of genetic flaws will manifest during this period, and almost invariably when they do they lead to the spontaneous termination of the pregnancy.  Deciding to clone, means a decision to go with a proven package.  Deciding to reproduce sexually means a decision to roll the dice.  By any reasonable accounting standard, a proven package should prevail.

2) A medical history.  While one might debate how much one's genes may shape their essence, when it comes to most known medical conditions genes play a prominent role.  Knowing the medical history of the clone's foreparent, can only enable that individual to take appropriate steps and make better lifestyle decisions.  This represents a gift that no sexual parent can truly offer their own offspring, at least not to this degree.  Far from a genetic prison, this knowledge will set the free.

3) Memetic exploration.  Perhaps the real meaning of cloning will paradoxically manifest not in the worship of genes, but in the realization of how freely we can choose a path once we each have complete self-knowledge of our own genetic packages.  At this point we will even begin to exercise control over our memetic environment as well.  Our ability to parse genetic meanings will make memes appear all the clearer to us then.  At this point, the individual has completely emerged with all the necessary knowledge and capacity to partake of the transhuman voyage.
