"3 apples" is just a rough (though often useful!) and very context-dependent abstraction anyway. real-world apples differ in size, so you might want to count a small apple as half an apple; and does a big "twin"/"conjoined" apple count as two apples? at best you're using some arbitrary size treshhold. it gets hairy/edge-casey pretty fast... i know this is nitpicking, but i think when you really look at it, "infinity apples" isn't that much more of an "idea" than "3 apples". (even if the latter is more useful in day-to-day life)
