comment How to introduce type theory to newcomer
@cody I've take a look at some references, primarily to the Homotopy type theory book and to The seven virtues of simple type theory. The first reference doesn't clearly address my issue while the second seems to tend to the second approach (the one which takes also dependent terms).

comment Homotopy Groups for Categories
I wouldn't dare to call this constuction $\pi_1$ of a category, mainly because this is structure distinguish an n-tuple of composable arrows in the category and their composite....

comment Why is this not a category?
A little add: if instead one consider the families $mor_{\mathbb P}(O,Q)$ of decreasing monotone functions these data do not form a category.... well not in the natural way.
