This analogy to "storing information" in the digits in pi is simply incorrect. The reason why it's incorrect is that in order to "store information", your access key must by definition be smaller than the data you are storing. This is not the case for "hiding" things in the digits of pi. In general, the index offset needed to find something will have more bits than the target information. This is clearly not the case for storing information in a blockchain as you only need a small index to find the transaction.
