Starship as passenger transport point to point on Earth is a nonstarter most likely, even for civilian applications.
It looks just like an ICBM, because it is an ICBM. I doubt Russian and Chinese air defence forces will wait for them to land and see if it’s full of people or plutonium before launching a retaliatory strike.
Your missed the part about parachutes. Also about flyovers. No landing would happen.
(We've been dropping people and gear for 100 years by plane. And yes, it can be done with Starship.)
On the side of civilian transportation, there is nothing to stop normal passenger planes from having nukes on board. The shape of the object is irrelevant.
