An example of what I'm talking about is the difference between gifts and loans. Say you're applying for a mortgage, and I give you $50k as a gift. Sure, you can use that as a down payment. But if I make you agree to pay the $50k "gift" back as a condition, it's not a gift, it's a loan, and calling it a gift is mortgage fraud. No matter how you word it, you can't change a loan into a gift.
Just like with extortion. Extortion is an act, and you can carefully word it all you want, but it doesn't change the fact of extortion, but it may make it easier or more difficult to prove.
But I'm not trying to say something especially deep here, just that it's common for people to look at the language of the law and believe that they can avoid consequences by rewording a few things.
