Whoever said, you have to do what is right for you, was right on. There are two sides to this coin...
If you have a job that you love, plenty of free time with that job, and are living life to it's fullest pre-retirement... there's nothing wrong with working your whole life. I think there is a good chance I'll be doing something with financial reward as long as I can. For some, trading extravagant homes, vacations, and cars for early retirement seems nuts... and they're not wrong, if (all that stuff I said earlier in this paragraph).
If, on the other hand, you don't love your job, or it absorbs your life, or your idea of fun/fulfilling life doesn't necessarily cost a lot, then by all means FIRE.
My mom "retired" at 46... but not long after that, she pursued multiple more-fulfilling careers than her first(one after the next). She currently makes around ~70k per year, and I think she donates ALL OF IT! But it has her traveling all over the Country, she sets her own hours, and she finds the work rewarding. She's now 67.
Just because there are a bunch of us who like the idea of LBYM and FIRE, doesn't mean it has to be right for everyone. They're not wrong, just doing what's right for them!
