Because your immune system is like car (and not like a muscle).. if you eat healthy, exercise, etc to keep healthy, your immune system can be fully operational and tuned (and unlike a muscle you can't improve it over its "peak" level) but it will still be susceptible to the flu because it doesn't have any antibodies for the flu. It will be able to fight it off better, manufacture those antibodies faster, and have a lower overall impact than someone who isn't sleeping enough or eating the right foods to provide the system what it needs, but it won't be immune until it actually encounters the flu strain.
Not to mention your body kicking the immune system into high gear to fight a flu has its own set of risks (usually for those more impacted by the flu in the first place).
So why not get those antibodies with a flu vaccine. Easy, takes a few minutes, and it's another angle of defense.
Plus you are better protected for those times when you have to work late or can't eat well enough or do whatever happens in life that can weaken your immune system.
