At the risk of sounding heretical on a RE forum, I think it is not a such a bad question to ask. But I think a lot of the answer depends on your definition of your job or work, especially whether you own your own business.
When I was in my 30s, I was just starting my own business. I actually got work doing things I was doing already (uP data acquisiton, processing, modelling) on my own projects. In fact I got hired for some jobs because people saw what I was doing on my own. So I just got to get paid for doing what I was doing already. And thought that was pretty cool. And in addition, my work exposed me to many other aspects of technology and industry that I was not familiar with, and I got to do many more exciting things than I think I would have been able to do completely alone.
Now I was not FI at that time, but I don't think it would have made a difference. I was too excited about starting my own consulting business and the projects I was doing. And others I knew then, one who was a superb engineer, who could have RE, with family wealth, started his own business at the same time, and it is still going strong. We worked togehter on a number of projects. He went on to get a large number of patents, travel around the world giving lectures at scientific society meetings, working with the best physisists in his field. Things he likely would never have done otherwise.
I knew another guy with great family wealth who's whole family worked in real estate development. I often wondered why they didn't just invest the money and relax, but it was not in their nature. They enjoyed what they were doing.
Another man I knew and worked with, had started a health device business in the 1950s, was still going strong into his late 70s. Still making 10 year plans for his business, starting into new ventures, talking about the latest scientific literature to scientists much younger than himself. I once asked him why he did it, he clearly had accumulated enough to live in as much luxury as anyone could want. He told me he simply felt he was making a contribution. But I think he was simply having too much fun. He always seemed excited about the next great medical breakthrough.
On the other hand another guy I knew sold out a very successful software company for big bucks, could have retired and lived well. But felt he needed to start another business, sunk a lot of money into it, but it could never be as successful as his first. Think it just faded away.
And another guy made a lot of money selling his medical device to a big conglomerate. Made a ton of money, but later lost it all because he felt the need for a do-over in the same field. Never was able to make anything of it, lost most of what he had accumulated.
What about the running away part? I don't think there has ever been anything I have worked on, or anyone I have worked with (or lived with or partied with etc), whom at some time I wanted to say, take this ... and shove it. I got to get the heck out of here! But later I was glad that I didn't say it or do it. And often the short term bad experiences turned into long term good ones.
So is retiring early (or anytime for that matter) running away, or just running (or strolling) in a different direction? It really depends. Depends on the time (sometimes exciting things get old), the individual, the situation, the work, your attitude and temperament and most of all where are you in the timeline of your life.
It is not a bad question.
