If you are too incompetent/idle to get any of the 'outside' of the coin right, how can people be sure the printing on the 'inside' - the private keys - has been handled correctly? There is no way of telling without destroying the coin so trust is a key issue. Frankly I'm not exactly brimming with confidence you've got each and every ~30-char private key right for thousands of coins when you can't even spell your own name on the damn things.
