Yes I agree that it's kind of crazy to expect a person to both be a developer and a designer.
The code first approach doesn't' always work, but creating mocks in Photoshop or Sketch or whatever.. tens to be a waste of time as well, since these mocks are just images and can't really be purposeful after that. Some larger companies can afford that, many startups or small agencies cannot.
Plenty of tools are meeting in the middle, there are tools to generate HTML, there are tools to design responsively (which is a nightmare in static tools) and there are tools that take mocks and turn them into prototypes.
