Well, one of the biggest brakes on cloning is time. Another is education.

Clone armies? You'd have to grow them to adult size _quickly_, somehow give them training and basic education, _and_ manage to have all of those muscles work properly. Remember the months to learn to stagger, then years learning to walk properly, plus the constant body changes until you hit full growth, and having to retrain yourself for every one? (clumsy teenagers from growth spurts, especially post puberty?) Heck, just women becoming pregnant causes complaints about not being able to walk correctly. (shifting/loosening tendons and muscles, plus weight redistribution)

There was a grade B movie many years back about an island that had clones being raised for rich people to harvest organs after they grew up. That's about as close as you could get - you'd have to wait a minimum of 14 years for that clone to be a useful size.

With all that effort? It'd be easier to just work out how to clone individual organs instead. Cloning entire humans isn't likely to happen as much other than a novelty. Well, at least not for a very, very long time. It'll happen, sure, but mostly to make sure it works. Someone who wants twins, for example. They'll fertilize an egg, then clone it, then implant both. No moral or ethical wiggle room. Children are wanted, they just want two. Whether they're identical to start with, or different, doesn't matter to how they grow up.
