Maybe I haven't encountered enough of these discussions, but I can't recall any where such was skipped over. More likely that they thought it obvious that humans would freely provide access, as there's no reason not to. Or because those deprived of access is always orders more than those with access, they'll just help themselves to the means, and the outcome will be the same. Unless those with access try to stubbornly continue the restriction. It's just a very illogical thought in an era of abundance, and so only really worth mentioning for completion.
