Because the government does such a wonderful job with everything they get their mitts into?
You know what Reagan famously said. "The nine most terrifying words in the English language are, 'I'm from the government and I'm here to help.'"
Government regulation should be reserved for things which are incapable of regulating themselves. Right now I think the "scuba industry" does a pretty good job of self regulation. If the bodies start stacking up like cordwood, call me a liar and bring in the Government.
