Part of your argument was that there can't be an application for fast uniform pseudorandom numbers not just that xorshift by itself is not a very good PRNG(which I do agree with although it is an interesting sequence). If Intel, AMD and Apple add a xoroshiro or PCG instruction and it produces pseudorandom numbers significantly faster than accelerated AES on those architectures, how does that affect your argument? On the other hand, most simulations have moved on from random numbers to non-random space-filling sequences so the only non-CSPRNG application would be rolling fair dice for games and even there there is an argument to be made for CSPRNGs. So, perhaps I agree with you on the bottom line.
