That has been solved with more user friendly wallets. If you're using a Qt wallet you'd think you knew what you were doing. The Qt wallet actually even tells you not to do anything until it's done syncing so you must have closed that overlay and ignored that warning. User error, that's your fault.

This is a great example of why Bitcoin has failed: you do not build faith in a financial system by reportedly telling people that any mistake will have no way to correct it but they will be mocked for not being perfect.
