Elon still can’t run, because the states still have authority over enforcing the qualifications for president enumerated in Article II Section 1. The Supreme Court ruling only covers Section 3 of the Fourteenth Amendment for federal office holders or people running for federal office. I honestly like this ruling. The conservative justices ruled this way because they wanted to keep Trump on the ballot, but if they are going to do that no matter what, I’ll take the win. edit: added clarification
