Making a good income as a freelancer requires work. And clients. And paying attention to clients' needs. And spending much more time organizing your financial and business life. And dealing with work/life boundary issues. It's something I like to refer as a "job."
And he's certainly not "retired," as he seems to claim, if he's paying the bills freelancing. It kind of sounds like he's decided to take a major income hit in order to have more lifestyle freedom (aided by living in a place with lower costs of living). Which is totally fine! Especially when you're young. But that's a major trade-off, and not one that should be taken lightly.
