Also:
There is no genre of space fantasy. It doesn’t exist.
Says who? Is there an official list of genres that is set in stone for all eternity? Who made the list and why did they decide to add cyberpunk to it in the 1980s, but space fantasy is apparently strictly forbidden?
The people who write it, publish it, review it, and read it. Why create a new genre for something that already exists? Why create space fantasy when the object being called that fits in Space Opera. They create a new genre when there is something new and Star Wars wasn’t.
Yes, Lucas based on Campbell’s work, but that is just a compilation of myths and legends. Those myths and legends had already been used in other science fiction stories. Telepathy, telekinesis, and other ESP powers are so common that you can’t truly call yourself a fan of science fiction without knowing all the times they pop up. Isaac Asimov even wrote a story about a computer that became sentient and so powerful that it became God. His work is full of what you are calling magic and he is considered one of the three greats of mid 20th century science fiction, along with Clarke and Heinlein. I am not familiar with Clarke, but Heinlein didn’t shy away from what is typically called ESP either. And Star Trek and to a greater extent Space 1999 had beings with mental powers that put a Jedi to shame.
You are using the very things the science fiction has incorporated for decades to prove that it is not science fiction. That doesn’t really work.
