I feel like sci-fi writers have a lot to answer for in enshrining Musk as part of popular culture. For years now, there have been stories which make casual references to him. Stories which include inconsequential mentions of little pieces of worldbuilding like "the Elon Musk space station" may not sound like much, but they all work to plant seeds in people's minds and strengthen connections.
It also strengthens this bizarre impression that Musk is the "cool" billionnaire. No one names stuff after Bezos or Branson in fiction. But somehow, the idea that Musk is worthy of mention just entered popular consciousness and hasn't left. It's likely this has helped to embolden his own horrifically large ego and his legion of fawning fanboys.
