If you hand someone a million in cash. Then find out they gave you bad goods or an empty container, how do you get $$ back if they're long gone? want safety here? you'd probably use escrow or something. Not a bitcoin fan, more because of its fluctuating values, but this specific reasoning doesn't set itself apart from cash.
