You aren't trolling, but it is trivial to come up with larger numbers that are, in a sense, just as practical. Memory suggests that if the universe has a finite size then there is a finite amount of information that can be stored in it. "The states of data that could be stored in the observable universe interpreted as a hard dive" is a much, much larger quantity than size of the universe in Plank Lengths.

However, what if we want to theorise about what, if anything, sits outside the observable universe? You seem to be suggesting that it will always be finite, which is optimistic to say the least. Just because we can't observe something doesn't mean that it isn't real, and that we won't get utility out of modeling it. Infinity might be out there.
