Health plans to lose money if Affordable Care plan overturned?

I have to admit I don't understand this health plan stuff. Rush says Obamacare is going to drive private health care companies out of business. So why are they expecting money if Obamacare is*not* overturned?

WaPo Scare Story on Obamacare and SCOTUS RUSH: Washington Post: "Next month, America’s health insurance plans may lose $1 trillion in revenue." May lose. You know why? "One trillion is the amount of revenue that health insurance plans can expect to lose if the Supreme Court overturns the Affordable Care Act." Might lose. This is a story about health insurance plans losing money that they think they will have, but they don't have yet. This is total BS. You can't lose what you don't have. If you don't get what you're expecting, you can't lose it. You have to have it to lose it. They don't have it. And where's the trillion dollars coming from anyway? We don't have that. So it's a scare tactic, and this story is aimed right at justices on the US Supreme Court. So, folks, if I don't win the lottery next week, then I will lose $10 million. That's what the Washington Post wants you to believe. It's simply a scare tactic. Nobody has the trillion, including us, to give it away to any health care providers.
