I agree with the basic idea behind this post. But most of the worrying over architecture and paradigms should be done at the preliminary design stage, which should happen before you even think about coding.

It doesn't have to be a polished, detailed, or even good design, but it does need to be something that you can at LEAST loosely stick to initially and have faith in. If the design is flawed enough that coding progress is halted, stop coding and revisit your design.
