@ThisDinosaur - Yes, from consumer (earn-buy or spend-buy) to something else.
The above discussion (mainly on this page) seems to be about whether it's better to have a lot of apples (and almost no oranges) or a lot oranges (and almost no apples). That's a bit of a false dilemma though. Given an amount of fruit, I'd prefer an even distribution of apples and oranges. Having an effective choice increases optionality and optionality decreases cost and improves resilience.
If you're all-money and need money to solve all problems, then you need a lot of money because you'd be spending it even in cases where the efficiency is low. Conversely, if you're all-handyman and need to work to solve all problems, then you'll be working all the time because you need to even if the problem could be solved more easily with money.
In more concrete/anecdotal terms, the way out of scarcity thinking is to diversify your solution space. When I retired from physics in 2009, I already had some experience with copy-editing. This was a job I found on craigslist on a Saturday morning, applied to, and had a couple of hours later. It was based on my experience with writing scientific articles. Because of all the other skills (or whatever the politically correct non-elitist term for ability is these days

), my cost of living was low enough that I could in principle cover all my expenses by working 4 hours per week if I had to, see

In the event of a broken hip, I also had 150k in the bank at the time. So in the event of a hip fracture, I had the money that were otherwise meant for FI to use on surgery. In the event of losing my freelance editing gig, I had the 150k in the bank to be FI. Of course, a twofer would have hurt me more, but that is less likely.
The other important observation was that it was hard to scale the editing job up. For example, if my monthly expenses had been around $2000 like the median person instead of $500, I would have had to work 20 hours per week and I might not have been able to find that much work. In that case, problem would be critical. However, it's a lot easier to find $500/month than it is to find $2000/month.
Later on, I started fixing up bikes. This was mostly for fun and I quickly learned that my monthly income limit would be something like $100/month. However, by the 3% rule, that corresponds to a "nut" of $40,000. This means that I could take 40k out of the bank and compensate for that with the bike hobby. Also, bike fixing is a marketable skill. I became the go-to guy at a shelter for the more technical problems. It's conceivable that I could have turned that into a "real job" as a bike mechanic.
Moving on. The blog+book eventually started making money. I didn't expect that (it's a rockstar profession) and it has never made over 40k ... so again, if 40k is what you spend, blogging for a living is extremely unlikely. OTOH, if 5-7k is what you spend, it's not entirely unrealistic. Shortly thereafter my financial rants landed me a real job in finance. This certainly paid more than 40k. I stayed for a few years. When I stopped, I was offered a few hundred bucks to do some furniture repair within one week.
So based on this experience, I strongly feel that I'm capable of picking up a low-medium three-digit income whenever I need it. This removes the scarcity mentality for me. I think doing this requires two attributes: 1) You need to develop some skill to a level where it's beyond what people believe they can figure out on their own on youtube. This means you gotta put a few hundred hours in. Of course, the more money you're looking for, the more hours. (My finance job was not based on few hundred hours). 2) You need to actively look for ways to turn that skill into cash.
I find that many are content to do none of the above and that many who are content to do (1) often have no interest in doing (2). I feel inherently driven to become good enough that people offer to pay me and I consider this payment a validation, so 1+2 comes natural to me. If that combo doesn't feel natural to you, I highly recommend trying to make it so anyway. I think that having at least one (and better several) marketable skills and selling one of them at least once will do a lot to remove scarcity thinking because you now know that you don't need to have all your eggs in the stock market basket hoping that as long as the basket is big enough, at least some of the eggs will survive.
In that regard, I do recall that the single-salary accumulation-crowd ("I need a gazillion dollars to feel safe and the stock market will always provide") suddenly became very quiet in 2008/09 after shooting down the idea of diversified income sources before that. They became loud again with the QE-based recovery, but ... it kinda goes to show what their risk is and how they feel about it when TSHTF.
I think a lot of people in the accumulation mindset will outright dismiss this idea, e.g. "Why should I bother spending all this time making $100/week knitting fake beards when I make $1000/week in my day job. Waste of time!". They're still in an accumulation and salaryman mindset and don't recognize the value of diversification when it comes to income yet. A workman mindset would never complain in such a way.
One can imagine a metaphor. Having just one money-making skill, it's like walking into a forest only recognizing the apples and figuring one better needs to pick as many as possible. Having many skills, it's like recognizing many sources of food in the forest, roots, leaves, berries, ... it's hard to feel that food is scarce then. However, it's still good to have a stash of food stored even if you can go out and find food whenever, because you might fracture your hip, eh?
