Seems like a bad idea: adding wealth destruction to a currency that is deflationary by design. Meh, we're talking about a tiny fraction of Bitcoin. Plus since Bitcoins are essentially infinitely divisible if you destroy a Bitcoin you're essentially just increasing the value of everyone elses' Bitcoins very slightly. Your solution requires numerous transactions, which a) bloats the blockchain unnecessarily, increasing costs for everyone else, b) also costs you Bitcoins in the form of transaction fees, c) takes a long time to complete. The OP_RETURN Script opcode allows you to include arbitrary data in a transaction, and that's exactly what an existing solution, Proof of Existence, does: http://www.proofofexistence.com/about http://www.proofofexistence.com/about
