Even if I accept your premise that he's doing all this because he's made a conscious decision to "help others and be content as a person", wouldn't he be in a better position to help others if he had millions of dollars to spend?
If his heart is telling him that being content is the most important thing, then why even try to play football anymore? Especially in a league that forbids you from smoking weed?
Again, imagine his life with and without weed and tell me it's not a problem.
