Because recreating such conditions isn't possible, basically because such conditions never existed and the idilliac setup the article seems to describe never happened. The article seemingly conveys (at least to me) the idea that "by miracle" all those famous philosophers, writers and mathematicians were in the same place at the same time (and possibly had coffee or dinner together), this simply never happened. So, if the idea is about creating brand new conditions (which ones?) capable to create a city/location where - over three centuries - a handful of people, excelling in their field lived, this has already been done, let's say Rome 200 BC - 100 AD, London 1600-1900, i.e. more or less the capitals (administrative and/or cultural) of large empires that lasted several centuries.
