מוקצה מחמת גופו would be coins on Shabat. But that itself is an argument between Beit Shamai and Beit Hillel concerning  bones. To Rashi that refers to bones that are totally inedible. And yet and thus. מוקצה מחמת גופו. In the Mishna Beit Hillel forbids and then the Gemara turns to Mishna around so that Beit Hillel turn out to be the ones who permit. And that goes along with the regular law that to R. Shimon Muktze only applies to Yom Tov. 

Still there are opinions in the Gemara that limit what R Shimon says--even though everyone agrees that the law is like him. So I have never written about this because people that want to be strict have some opinions to depend on. It is just that I am not looking for ways of being extra stringent. What the Torah forbids is enough for me
