There's a lot of range of what constitutes "independently wealthy, i.e. can live off interest of their own savings" when one gets there. Say, you may live a single life of relative leisure for the rest of your days, but if you plan to start a family and have kids (with all it implies) - nope, you'll still have to get back to work! Or want to live large and not have to worry that much about material side of life (i.e. when money is just for keeping score)? Well, you'd better find out ways to make most of your current financial independence to get there, which in itself is work (although just investment related kind, but still).
