Dear Daryl,
Thank you for your deep, great comment!
I was happy today when I read your comment in the evening after work. This is the best comment of my essay, and not just an essay, but for the whole period of my philosophical travels in the foundation of the world of physics and mathematics.
I agree with you completely with your conclusion about the difficult path of physics in the way of the foundation and "building" physics. I agree with your good figurative metaphor of "carpenter", as in my youth I myself worked as a carpenter. The walls of the building, we always started to erect a "corner". Wise words Grosseteste and current situation of the philosophical foundations of basic sign systems - Physics and Mathematics, said that the problem of understanding is central to the whole system of knowledge. G. Gutner good understanding of the problem revealed in the article "The ontology of mathematical discourse", "event which consists in grasping the structure, means understanding." The main question in physics (and mathematics, as it is already too high climbed to skyscraper called "Ab-Stract-ion") - "grab" (understand) the first structure being (the Universe). I think what "angle" in the ongoing construction of the building physics - is still not "caught up" (not understood). You can say, physics found itself in an "angle", one side of which GR, the other CM. This is well told Lee Smolin in "The Trouble with Physics." And judging from the output of Alexander Zenkina in his work "The scientific counter-revolution in mathematics", that "the truth is to be drawn ...", that physicists need to draw all the "corners" of the building physics as a fundamental system of signs. This means as well said David Gross, should be built by joint efforts, "the general frame structure." http://expert.ru/expert/2013/06/iz-chego-sostoit-prostranstvo-vremya/
