IMO you have an oversimplified view of this based on limited experience. You have abstracted away the diverse and complex reasons this doesn't work for everyone behind the excuse that people make excuses. It's not so simple. People are different; their circumstances are different; we can't just write them off by blaming them for being obese or addicted.
