We've lost probably 3-5 million out of 19.5 million that's been mined. We've proved that we need better solutions. Multi-sig where one of them someone keeps for you like Unchained or Casa are best for the vast majority of people. I agree a screen to verify the transaction would probably be best, but then again I also bet after the first handful of times your average person doesn't check unless it's for a very large amount.
