Because not everything that you do in a software business is coding. Would you rather spend all your energy on coding and getting that thing to work or would you rather code a few hours and then try to sell your product and do team management for the rest of the time?

VCs won't go around looking for programmers to hire to implement their 'great' idea! Have you ever heard of a VC that said no to giving money to a company and then went and looked for a team to implement that idea? I'd also argue that they like it better if there is a business person in the team.
