No, mid lane has the entire map. Part of why you put certain champs mid is so they can go anywhere at ANY time.
If mid takes your jungle that means you are gonna need to invade or gank sooner. That may be a good or bad thing but if you are "carrying" it shouldn't be a problem right? You don't need to waste too much time on jungle anyways if you could be ganking. Your laner is probably safer taking that farm and you could go take theirs if you really need the gold. There's really no problem there unless you actually need the buff at that moment.
Mid has the entire map, jungle has a midlaner
If you need something ask the midlaner. Double ganks, invades, whatever. Or get the support or adc or even top sometimes. If someone takes the buff you should be able to get something out if, nobody owes you anything its just an opportunity for a jungler to take advantage of.
