Because the point is to "be your own bank". Think about it, if it was easy to recover lost bitcoin "passwords", then that would be a huge flaw that a lot of hackers can exploit. Using bitcoin and it's advantages also comes with risks, and this is one of them. It's your money anyway, why would you be so careless with your password.
I absolutely agree with this. The point is why even own a password and store it carefully if it can be retrieved in a 'jiffy'. This will certainly be a compromise to the originality and purpose of the blockchain advantage. With many bugs continually cleaned out this will be viewed as a serious scandal if this were true.
