Not a private plane, his private plane.

Evidence? This site says the plane is owned by Emes Air, whose parent company has a billionaire shareholder in the Bahamas (someone named Joe Lewis, not SBF) and is registered in Argentina.

Also even granting the money wired out was by SBF, not a hacker or someone else, I don't see how that's evidence he flew to Argentina.

+1, the only evidence we have is a private plane left the Bahamas and flew to Argentina yesterday. I don't know the base rate of private planes leaving the Bahamas, but I see a lot of people jumping to conclusions on this.
