Without making a judgement on anyone's business skills, this just comes down to cost. If a business person can get a good programmer to build his idea, all the power to him, but hiring a poor programmer isn't likely to be much better than learning to build it himself, and would likely cost a decent bit more time and money. Someone who doesn't program starts with the disadvantage of having to rely on someone else from the get-go, and until there's at least a prototype, executing on the business side of things is likely to be pretty tough. Sure, it can be done, but why choose to give yourself that disadvantage?
