When I read the headline at first, I found it quite provocative, but taking a closer look through Iyinoluwa Aboyeji’s comment, what I understood from a deeper perspective has more to do with entrepreneurship versus passive allocation.
And I, in principle, agree with the title of your topic, because investing is an activity for the lazy, because after an active action (purchase of an asset) no actions are taken for a long time (directly contraindicated), until a certain moment (receiving a profit).
Where I got interested and had some agreement with him was when he cited a well known figure like Elon Musk, who built his current wealth status primarily by deeply embedding himself in the grueling daily execution of his companies Tesla and SpaceX task, by being an active person, rather than operating as only a traditional portfolio investor.
I haven't been keeping an eye on him (or another lucky man who turned out to be an icon for the worship of many) to assess his performance at work, but he's actively
deeply embedding himself, though I doubt it's in his work.

This man has quite a few illegitimate children. Some, even with a coworker. Therefore, I have some doubts about his
deeply embedding in his work (only), rather than his colleagues (from whom there are also children).

I agree that investment is more for the realistic kind of person than it is for every kind of Tom, Deke or Harry.
And I believe that investing is suitable for everyone who has the money for it.

To me, this is more of a call to attention and a challenge to those who doubt their abilities and capabilities, to start their own businesses with the experience and ideas you have, because even though investment in any kind of asset including Bitcoin is a smart move to build long term wealth, building a business could amplify your wealth and change society in more economic and job opportunitistic ways than mere investment ever could.
Starting and maintaining a business is much more difficult and risky than investing. It's not for everyone, as 80% of businesses fail within the first year. If it were easy and simple, the statistics would be different.
So I ask,
Do you believe that investment is for lazy people?
For the cautious and rational, as well as those with insufficient capital to create their own business.
