(Though, now that I think of it, these days there probably are quantum noise generators available somewhere.)
AFAIK, there are but they’re way too slow for use in MC, so decent-but-fast PRNGs are still preferred.
Also, sometimes you need to run several tests with the same random sequence for debugging purposes, which with true random numbers would require you to store all of them, whereas with pseudo-random numbers you just need to use the same seed.
