Art sure, but not the most secure option. Would you not be nervous that the 1000 BTC could "magically" get transferred if the value got to high?
Don't get my wrong its cool. But this could confuse noobs about security practice and that bitcoin does not denote actual coins.
Bitcoin is not about art. I think you are conflating two very different things. Sure you have skin in the game having coins, but they are not secure, the whole point is security of value here. If the coin maker can sweep my coins I don't want them in that address.
