In the Three Little Pigs tale, the brick house is a non-exclusionary non-rival good, which can be modeled as a distributive category.

BH x (Pig1 + Pig2 + Pig3) -> BHxPig1 + BHxPig2 + BHxPig3.

It is very much exclusionary, at least before everybody is in: the door can be locked. But it is, certainly, non-rivalrous: each pig can happily consume the security it provides without taking anything away from the others.

Anyway, formal models of (non-rivalrous and non-excludable) public goods (such as safety) are well-developed. What exactly are you trying to achieve with your own model?
