Not being able to send things into space is not scarcity. Food, education, transportation, housing, healthcare, life's necessities.
Strictly speaking, this is false.
By the lack of being able to send much to space, we must not currently be in a post-scarcity society, because space exploration is such a good and exciting thing to do, you'd expect that it's one of the first things to get accomplished by a post-scarcity society.
You're making claims about how space things align with post-scarcity that doesn't match up with the accepted meaning.
Even still, we _can_ send stuff into space, now cheaper than ever. What is the threshold for "send much to space"? Any person can order up a rocket payload on Amazon.space and have it placed in orbit? That doesn't sound good even if it were free. Especially if it were free...
