I don't think anyone who says a billionaire shouldn't have power also believes that someone born into the right family should have power. Ideally those in power should be democratically elected by the people they hold power over and be protected from lobbying attempts by wealthy individuals. Someone like Elon Musk having political influence is a bad thing because he's raging capitalist that can, will, and does exploit those below him. It's why he has such a love for his Chinese labour force. They have less rights and they will work 16 hour days in his factory making the cars that make him money. Elon Musk is great as a wealthy private businessman, that's where capitalism firmly belongs. But he has no place in any sort of politics. Countries aren't run like businesses.
