It doesn't need to be some complex countermove/counter-countermove/counter-counter-countermove, etc., unless you're interested for arts' sake. Nobody actually fighting you will just leave their hand or arm hanging out there for you to latch on to.
Anybody can look like a joint locking magician during a demonstration, or against someone who is already submissive or too injured to resist. But try actually using it on someone who has even the slightest level of determined resistance, anger/agitation, and especially if they have a size or strength advantage over you. Various types of bodies/physiques are also more difficult to grasp, twist and joint lock than others. I'm mostly referring to the types of standing joint locks that rely on fine motor skills to apply; the type that many CMA masters like to smilingly show off at demos. Similarly, the old late 19th/early 20th century stereotype in the West of the tiny Japanese Jujutsu master easily subduing a large brute (or two or three at once) with an effortless lock (often using only one hand) was a myth and a marketing ploy created by Western Jujutsu teachers to promote 'the art of self-defense' to 'cultured' men and women, most of whom were not physically inclined.
