SEC (or other agencies) are definitely not tasked to explain the laws and regulations, they're not offering consulting services either. Coinbase can pay lawyers to explain the laws to them, or get in court (which they will, eventually) to get a judge explain it for good.
The last sentence sounds worse than it is. Because for questions like these, the courts are the ultimate grounds where different interpretations of the law get settled.
Of course, this different interpretation if the law can mean that one side is ik clear violation of existing, and well understood, laws and regulations.
