If you steal someone's BTC coins in this way - don't expect to be able to talk about it publicly. A judge might easily make a ruling that you "stole" the money. Don't expect the legal system to accept the notion that crypto is outside their jurisdiction, nor expect them to appreciate your complex tech arguments about why it's not really stealing.
