I see where you are coming from, and agree with you. I am happy to say I'm at a point in my life where I feel I will never have to worry about finances, and I'm nowhere near $10MM. I'm 30 years old, live alone in an apartment that could be big enough for my wife and a kid if I decided to marry and have a kid. I save/invests around 60% of my income. I'm not at $100k on savings/investments yet, but can easily calculate when that will be and it's not too far in the future. I work full time, and I'm looking to reduce hours/days worked before I turn 40, but maybe I won't. If I will, financial implications will not be the major factor of that decision.
So yeah, considering I'm comfortable with two or three less orders of magnitude less than 10 million... I'm as amazed as you are.
