I agree it’s hard to get the exact details of the MUH right, but pretty much any version seems better to me than ‘only observable things exist’ for the reasons I explained in my comment. And pretty much any version endorses many-worlds(of course you can believe many-worlds without believing MUH). Really this is just a debate about the meaning of the word ‘exist’.
