Coming from a banking institution, I can tell you what Blankfein meant in that context. They were speaking about regulation in the banking industry and how "oppressive" some bankers find it. Blankfein made the opposite argument, stating that regulation is a fact of banking - "no choice, no problem." In other words, there is no way to avoid strict regulation in the banking industry. Since it's a fact of life, so to speak, there's no reason to see it as a "problem." See? You don't have a choice about it, so there is no problem, or reason to feel "oppressed" by it; you just deal with it as a part of doing business.
InLooking at it in a broader sense, I believedifferent way - this phrase can mean that when you have real, difficult choices to make, they tend to be seen as problematic. See this book: Read the last paragraph on page 24 and the first on page 25, and you'll see the context. When you have no choice, you have no decision to make, and therefore no difficulties in making, implementing and living with the consequences of that decision. With choice comes the responsibility of choosing.
