I think that financial independence is the definition of retirement. It is only seen as a mismatch (and early if before the age of 60 or so) because the conventional path to financial independence is working for 50 years. Someone who has spent 50 years working and is now financially independent will not want to do any more work ever again. Someone who is financially independent at the age of 26 or 30 though will probably keep working. This doesn't mean that the latter person isn't retired; an unconventional path to retirement leads to an unconventional retirement.
