If the majority of the population thought that way, we'd have an economic collapse though, so forget what I said.
In fact work is preferable to how I spend a lot of my free time. Would I like to work more flexible hours and get paid the same to work 30 hours instead of 37.5 a week then sure, but otherwise what would money be buying freedom from?
I suppose owning a house out-right would be freedom from worrying about security of housing, and having a large cash reserve in a few currencies would be security from political instability.
Perhaps that I only have to worry about these "big" things means I already qualify as rich from my existing income, but "not working" is definitely not a goal I align to (yet).
A diverse portfolio is better protected against inflation, cash ought to make up some of a diverse portfolio but not a large proportion of it. Bonds are a better way of having cash-denominated assets since they still have returns while not being particularly risky (in the general case).
Cash is still useful however because it is easy to access quickly without losing value to having to sell quickly and doesn't incur fees.
Most of the work we have to do is not life changing or world changing, or even makes the world a slightly better place for anyone other than the ownership.
One day you might want to fully explore a new technology or framework, but your current work environment isn't interested and you aren't well versed enough, or there aren't any jobs in your area related to that technology. Spending time after work is an option, but when you get older and have a family, the harder that is.
To me money is freedom to not have to work, or be able to work on what I want to work on, explore what I want to explore, etc.
...or a much better society.
1) That you have to trade your health. I wonder if lawyers at Biglaw live longer than the bottom 75% of income earners. My opinion is that they very likely do.
2) Smart isn't applicable to the context you set up. It's dependent on what you want out of life, these are personal life choices. If I prioritize money over life expectancy, and I get rich but die at 63 years of age (due to the work lifestyle I undertook to get rich), that was my subjective choice - smart doesn't enter into it.
3) Most people with careers trade their youth for work to some substantial degree. The exceptions are extremely few, and extremely far between. Just working 35 to 60 hours per week, from the age of 20 to 67 (the soon to be social security retirement age), is heavily trading your youth for work.
2) The article makes the assumption that because wealth doesn't correlate to IQ very strongly it must mean IQ doesn't help you become rich. My point is that doesn't necessarily follow and it may be that smart does enter into it - maybe nearly every smart person could get rich and decides there are better ways to live.
3) There's trading your youth and then there's trading your youth. I would say a guy who works 40 hours a week and has other interests does a lot less of it than a guy who works 60-70 hours a week and does nothing else.
My biggest concern isn't that you can work away your youth and health like that, it's that a lot of people of my generation have no idea that's what they are doing and were gently coerced from a young age to imagine the house/car/work triad as the three ticks of success in life.
I think for a lot of people, they don't want to compromise. So if you are thinking "I need X so I can live in the wilderness and write books without having to worry about a job", then they put off writing books until they are rich. And by the time it happens (if it ever does -- which is rare), they find that they don't like writing books, and their spouse, who was attracted to them because they are rich, refuses to live in the wilderness.
Compromise is the true short cut. It allows you to start now, with less resources than you would like. It then allows you to build your life so that the thing you wanted is part of it. Even if you need a lot of money to achieve your ultimate goal, remember that it needn't be your money that you spend.
P.S. Even if your dream is to sit on the beach every day and get drunk, I assure you that this is very common amongst the poor ;-)
