This person is in the early stage of their career. Building the skills, network, and reputation necessary to carry them through the rest of their career while they are young and energetic _is_ working to live, particularly at a FAANG. Nobody wants to become a 50 year old with the skills and experience of a 30-year old.
If someone with the skills of a 30-year old can eek out a good comfortable living without much effort, what's wrong with wanting that? Most 50-somethings I know are doing basically what they were doing at 30.
