But you can write it down, even as a straightforward number, without any 
problem. Perhaps a googolplex (10^10^100 iirc) would be difficult to write 
it down in full, but I have just represented it as an exponent with little 
difficulty.

These bigger numbers can't be written down, because there will never be
enough material, even using multiple systems of exponents.

(A few years ago the biggest number I'd heard of was Skewes' Number
(something like 10^10^10^34), but even that is trivial to write using
conventional exponents as I've just shown. Graham's Number is in a different
class altogether.)
