As I said in another thread, U3 SD cards in such a large quantities are $1-2 (if that) for 32GB up to $4-5 for 128GB. U3 is rated at minimum reading speed of 30MB/s, which is about what PS5's BD reads at.
So yeah, they could've made that physical card that requires install to be other option instead of GKC, with current high speed game cart as more expensive option.
