The closest thing I can think of to the removed word is not "of" but the Spanish "hay" (pronounced like "I"), which has no clear English analogue, but it means roughly "there is" or "the present state of affairs includes". The talks failed because hay politics (there is politics), the sandwich is delicious because hay bacon (it has bacon), you should go to the planetarium because hay space (there is [the profundity of our relationship to the cosmos]), where in the last case we also consider the context of the word "space" (nobody would here say "because cosmos!").
