Jonathan,
A basic premise to consider is the process and relationship of expansion and contraction/consolidation and applying this physical dynamic to the evolution of knowledge and society. The kind of play you are emphasizing is a mental expansion and the flip side of this is the knowledge and principles which coalesce out of this expansion stage.
I think there are two aspects of this to consider; First is that expansion is wholistic. Like a balloon, or light expanding from a source, or even flowers and children expanding out in the spring and youth of their lives, it is relatively formless in the sense it is non-judgmental and simply absorbs what is in its way. Consolidation is the opposite. It is constantly congregating into points and areas of attraction and structure and is mentally judgmental and structured.
Now secondarily consider how this dichotomy defines much of what you are describing, both good and bad. All that structure and pressure modern society puts us under is also the accumulated wisdom, rules, assumptions, instructions, desires, judgments, etc. of those who came before and the monetary and economic pressures are similar assumptions and expectations of a society which is slowing and looking for sources of fresh energy and insight, but drown those little buds that do poke themselves up under a great deal of blowback and judgment. Even dealing with professional scientists, I find a great deal of preformed opinions which occasionally seems to me to be herd mentality, but to their proponents is received wisdom. Right now that playful tendency that is out on the cutting edge of theory is dreaming up multiverses and multitudes of extra dimensions, etc. Should this prove to be unsustainable, it will contract into a harder and more judgmental set of principles which prove more stable and viable, because that is the eternal process of expansion and contraction. Those flowers will bloom in the spring, harden into solid growth over the summer and die back in the winter, only to bloom forth again in the spring. So rather than just encourage that wholistic expansion, also put it in the larger context of what came before and why it is what it is and that might better inform us of what still might be necessary efforts of future growth.
