This works fine for off/on states, but not graduated ones where a range of input is needed. Muscles are binary -- they are off, or on. At least, at the cellular level. But when they're put in bunches, only some are activated while others are not, which leads to a range of possible force levels. Effectively monitoring neural activity here requires a large number of sensors to accurately determine how much force is being requested and then translate that into a digital representation. As well, do not forget t

No. You have some facts that are correct, individually, but you are drawing nonsensical conclusions.
True, individual muscle fibers are either contracted or relaxed--on or off as you say, but surface electromyography records from far more than a single muscle fiber. So at the population level, measuring a graded response is not only possible, but typical. Furthermore, the signal recorded is roughly linear and proportional to the number of fibers and motor units recruited (let's ignore the differences between type I and type II skeletal muscle fibers for the moment).
Your aside about the sympathetic and parasympathetic nervous system appears completely off topic.
