This would only work of the information were meaningless and a-
signifying. I can write a whole book with just the words "The movie
Goodfellas". Anyone who has seen that movie has a rich text of
memories from which to inform themselves through that association.
That is what being informed actually is, associating and integrating
presented texts with a body of accumulated texts and contexts. If you
conflate information with the data that happens to be associated with
a particular text in a particular language-media context, you are
literally weighing stories by the pound (or gram).

Besides, any such quantitative measure does not take sequence into
account. A book or file which is completely scrambled down to the
level of characters or pixels has the same quantity of entropy
displacement as the in tact text. To reduce information to quantity
alone means that a 240k text file can be rearranged to be 40kb of
nothing but 1s and then 200kb of nothing but 0s and have the same
amount of information and entropy. It's a gross misunderstanding of
how information works.
