What exists, in his view, is the ring Z/nZ for some n (larger than what is physically possible to compute).

Less flippantly, I take your point. Mathematics as a whole is quite arbitrary, which also makes it feel more freeing in a way, but also more depressing because the “dialectical forces” which drive its development tend to come from people and fashions rather than fundamental reality. The rules of logic seem universal to me (inb4 constructivism).
