I feel like being "content" involves a lot of other factors and trying to determine if someone is content means looking at other aspects of the job holistically. I've always detested yearly evaluations and the 'song and dance' one must do to write "corpo-speak" about their achievements and goals. Yet, that consistent displeasure has never outweighed the work life balance I've enjoyed so far. My concern is that in your framework I would be considered by definition, not content.

I don't see jobs as fungible. While you might be able to WFH the new company will have different benefits such as potentially worse health insurance, compensation that isn't as good, or fewer paid days off. You might end up working remotely for a company in another timezone and that might mean you cannot drop your child off at school anymore. That kind of thing.
