The most damning thing I've seen on starship was a video that described how little space there is inside for the humans Elon said it would hold. Something like urban transit personal space.
That is practically all spaceflight. The Apollo LEM - which landed on the moon - had ~2.3 m^3 per person. The command module had ~2 m^3 per person. There is nothing unusual there and depending on how you configure the interior it could be relatively spacious.
