How do you know that enabling people who happen to have resources in one of the current political regimes to edit their embryos will reduce suffering? It could just as easily increase it.
It's not a matter of enabling this at the regime level. Regimes get to make their own laws. We in the west may not be able to stop clearly unethical embry editing, so whether we can do that or not is completely orthogonal to whether we should consider some uses of the technique to be ethical and allowable.
It's a source of suffering that can be solved through genetic engineering of embryos that some group of people with resources will be inclined to address.
It is relevant because it precisely fits your criteria.
