Information Systems Architects should write solid code. Part 1, Why?

I believe that an architect, in the Information Systems world, should be first and foremost a very good programmer. The architect should write code on occasions, it would be better if writing code is actually a habit. When this is the case, the Architect is able to bring a positive influence to the organisation. When this is not the case, the Architect would most probably be less efficient and will find himself/herself regularly in unproductive discussions.
