You completely missed my point. 'Collateral damage' will be oxidation. The human body has remarkable abilities to deal with oxidative species via mechanisms such as superoxide dimutase. My point is that this warrants further investigation. ie. Less fables and more research.
As for the money, well this is easy to see:
$20 x 10,000 people = $200,000 USD. This is barely enough to fund one person's retirement.
