> Everyone knows if you save starting in your early 20s compounding interest it will be worth a ton more in 10 years, 20 years, etc.

How are you expecting to get a ton more after 20 years? Even with a ridiculous constant real interest rate of 5%, you'll get only 2.6x your original investment after 20 years.

Well, if you start out with 400kg, you'll get a ton after 20 years, based on a 5% growth. :)
