> A developer doesn't need to have skills if the developer has the resources to obtain others with the needed skills.

A person who does not have any development skills is not a developer. The ability to hire developers does not make one a developer. If I hire someone to play some Rachmaninoff for me, am I a pianist?

> For example, if you want to create an e-commerce site then there are lots of hosted services which will set one up for little to no cost.

If you rent a hosted service with an off the shelf e-commerce site that is automatically installed by your hosting provider, you are not a developer, you are someone who has instructed a hosting company to set up an e-commerce site.

Now, you don't need to have any development skills to run a successful online business, that much is true. But you do need development skills to be an actual developer.
