Well, the guy and his motives are unknown to us all. We can only discuss him as an example or a model, not as a real person.
But if cycling is more important to him than a high paying or high status job, then he would be stupid to give up cycling to get a job he doesn't really want.
Cycling is very versatile. It can be a relatively small part of a high-pressure materialistic life, or it can be a bigger part of a simpler life.
IMO, we should all choose the path that will make us truly happy, rather than the path that society believes is best. But as long as this guy is staying off welfare and paying for his bike habit, I think none of us has any right to criticise or disparage his life choices.
