I wrote out the easiest solution in another comment in this thread.
If you're a native English speaker, you can go work for $20 to $30 an hour for 10-20 hours a week a few months and then live for a year or more in dozens of countries on the savings.
There are many other solutions to quitting working, but that is the easiest one that you can start tomorrow and be finished within 2 or 3 months.
If you have more specific criteria for quitting working, I can give advice specific to you.
Geographical numbers vary but let's say an office worker needs something between 1200–2700 eurodollars per month for expenses. They might have a loan on their housing or they might rent. Maybe they have some hundreds, or even a few ten thousands in savings generating a bit in compound interest. They like to live where they live or live half of the year there and the rest elsewhere or have a few vacation trips. Maybe they'd want to spend the time not working anymore with their family, or enjoy culture, or learn new things, or keep themselves functional by exercising. Maybe they find a volunteer group that does something meaningful to the world which could take time.
Another case could be some sweatshop worker, where the daily pay is a bowl of food. No cash income, no higher education.
Personally I'd agree on similar values and goals but my personal anecdote side tracks from the point of an accessible solution to anyone. Even I'm in a more privileged situation than an average human and still have issues with the income-expense equation yet to solve, not for a lack of trying.
I don't have that argument (or any arguments) in any of my comments and I don't believe there's a single solution to everyone.
I have only been interested in the framework that relies only on trying to see if there's anything new to apply to my or any different situation.
Clarifying(?) edit:
Sure I think I see you champion a mindset shift, and that is definitely what most people would first need. In addition to that, there's hard math that needs to work. Similarly; a person might want to become an entrepreneur, they have that anxiety or fear of leaping to the unknown I detect from your message. When they cross that barrier, they also need to have the numbers which are sustainable. A wonderful can-do attitude and trying again and again but with failing numbers isn't enough.
