If your number is on the order of $10 million, I suspect that no, you wouldn't, because you haven't thought hard enough about retirement and how to achieve and keep it with a satisfying lifestyle to realize that you don't need nearly so much (or at least most people, maybe you have a need for very fancy things, I won't judge). And requiring $50 million at a
younger age? What's the logic in that? The younger you are the lower you can set your number, because if you end up being wrong either about the feasibility or about your mental state from not having a job, you still have time to fix things or even pivot to a new career. (You also get more years of compound interest.) I quit my BigCo job 5 years ago just before my 30th birthday with ~$500k across VFIAX and VGT, I've been "retired" since and that amount has grown considerably. I'm still quite happy not working for someone, while still being reasonably confident I could get a programming job again if a need or desire arose, and there's always the possibility of going a bit crazy and burning through it all to self-fund hiring some employees of my own to make a go at a business.
It's not hard for me to understand why people keep working even if I'm not and don't want to be that way. There are so many reasons, I'll list a few, some work just as well even for people who are working despite having "enough", whatever that means. Some people just really like having a job, or think of it as a moral duty (and themselves as doing good by fulfilling that obligation), or some get their self-worth from having a job, or some like being occupied by work when they know that without it they'd just rot. Some like the social company. Many actually like their work a lot more than they dislike it and pay above some threshold is just "nice". If you're particularly good at your job, too, there's a lot of joy in doing things you're good at, no matter what kind of job it is. Some have expensive tastes or have made expensive compromises or have fallen on expensive bad luck that all can need ongoing funding. Some want to make or support things and need capital to do so. Some just see life as a game, and money going up is their source of happiness and sign of winning. There's all sorts of minds and preferences in this world.
