I think you overemphasize the connections. The ideas you mention are indeed present in HPMOR and also in Dune, but that isn’t surprising. Say there are 100 not-mainstream ideas in HPMOR and 100 in dune; it is surprising that 4 of them overlap? No. Even if there are only 10 not-mainstream ideas, if 4 overlap that isn’t surprising either. After all, it’s rare for any book to have even one idea that has literally never been explored before.
That said, I like your list of connections, and I do think it is evidence that Dune influenced EY, and I do think that people form a lot of their worldview from literature they find inspiring—but also which literature they find inspiring depends on their worldview.
