Presburger arithmetic comes up naturally in the theory of stochastic discrete chemical reaction networks, specifically, in questions of reachability. E.g., with some given set of reactions, starting with exactly 17X and 8 Y, is there a series of reactions that might occur to bring the state to being exactly 1 P and 2 Q ? This problem is (but for notation) identical to or equivalent to reachability questions in Petri Nets and Vector Addition Systems, but for me, the connection to fundament chemistry makes it more “natural”. The connection to Presburger arithmetic can be found in the extensive and brilliant works of Jérôme Leroux, for example (but also see his more recent work):

For some out-of-date background, forgive me for self-citing:

And for a more up-to-date view of the connection to chemistry:

Of course, I imagine that you may be thinking of “natural” in terms of mathematical naturalness…. and even here I think that the Vector Addition System formulation might serve your purpose.
