If your cash was stolen from your wallet, how would you prove the cash was yours? Besides, I think most "mainstream Bitcoin users" have their wallets on sites

  Or, as onli suggested, you can provide the private keys for the emptied account(s).

    No, you don't want to give away the priv keys, as someone may transmit a future transaction you could claim with it. Simply signing a message would be sufficient. Don't reuse the 'k' value with your ecdsa sig!

      Of course, you just have to prove that you know the private key. Handing it out is unnecessary. My bad. BTW, instead of signing a message, you could also move around some money through that account. This may be easier to achieve for non-tech people, as it can be done with any Bitcoin client.
