1600% higher returns can cover a lot of eventualities.

it doesn't cover you getting disabled so you can't work anymore at the age of 30 after working 8 years.

1600% higher return is great when you work from yours 20s to your 50s/60s and can essentially self insure yourself at that point with it, but as the person you are responding to you is (I believe) trying to say, that's not everyone.
