Then anyone who gets the document, gets the key?

  So what? Worst case scenario, the attacker gets control of the BTC before the user can recover them, but that's no worse than the original proposal, where the value would always be lost

    Well, how could you prove that you were the one that inserted the value into the blockchain? If anyone can have the key, anyone could have inserted it.

      We are talking timestamping here. If any money was ever sent to the address generated by the hash of the doc, even if the current balance at that address is zero, proves that that document existed at the time money was sent. Why care about ownership?
