*Playing Devil's Advocate
Unless a concept is assigned something to represent it. Any form of symbol. Infinite has been assigned a symbol with no numerical value, but with a numerical concept for which is was assigned. When infinite is considered within numerical parameters (not just "everything"), infinite is represented in mathematical equations by a symbol. Certainly the concept is infinite, but the symbol is concrete, and may be used to express variations on infinite (though in reality there are none). So uh, yeah... I give up, nevermind.
I guess my original reasoning was nothing more than an expression of the difference of two numbers in relation to eachother alone, then adding the concept of infinite. Not actually comparing those numbers to infinite. Ok, I'm done
