That isn't nonsense. I can easily abstract the notion of a set containing a finite number of camels to a set containing all the finite sets of camels. If I then ask how many camels are in this set of "all camels", I also have to think about what kind of number is the sum of all finite numbers, of camels or any other kinds of discrete objects. What I think is the real problem here is an inability to abstract. That would be: from your corner.
