It's an important plot element that Lelouch is ALWAYS facing some adversity. Even when things are comparably looking good, there's always shit lying in wait, ready to blow and take him down to nothing. At every point of the series there was either something fucking him in the ass, or something about to explode in his face. Sometimes both.
I notice (and relate to) this because my life is somwhat similar. My only aspiration is to support myself and be as lazy as I can be, and yet almost supernaturally, I encounter all these little problems along my plan that, for all intents and purpose, was tailor-made to avoid this stupid shit.
