Sorry, but that is just not entirely true.

First of all, storing a hash is not storing the file. The OP specifically asked for storing a file and not just recording it's existence. What if someone wants to store a file that will be there even if all his computer equipment is destroyed?

Also, you can save all those files on the Blockchain fairly cheaply - no 100,000$ needed.

1 MB data can be split up on 8192 1-of-3 transactions using 2*64 byte from the second and third public key.

I am not sure how much overhead comes with each of those ... let's say it's 300 byte per transaction to calculate easier. That would make the 8192 transactions a total size of 2,4MB including overhead. Currently, 0.00001 BTC/kB is enough to get your TX confirmed. That would be 0.024576 BTC to store your 1 MB file incl. overhead.

That is 195.90 USD, not 100,000.00!
