The problem with 'intentions' is they are only that: intentions. For example, most 'experts' intend to help us by telling us that it is heart-healthy to eat a low-fat diet. But that may be the consensus, but it is as wrong as the global-warming 'consensus'. As an example, after years of drugs and dieting and no improvement, my wife finally dropped her triglycerides from 240 to 79 in two months, by eating a low-carb, HIGH-fat diet... and with no drugs.
The point I want to make by this example is that central planning is too rigid, no matter what the intention is. When he consensus is wrong (as it is here, and is likely the very cause of the obesity epidemic), it adversely effect millions of people.
Like it or not, you must let people think for themselves. There is no free lunch-advice; you yourself must decide what to eat; you must decide what to do and what to think. Remember, just because someone works for the government doesn't 'necessarily' [read that sarcastically] make them smarter than you.
