But think of it this way.
Starship is huge. Docking it to a smaller massed station could be a problem. Its reaction jets could actually push the station away instead of just slowing down the Starship.

Plus there will be far more customers for a smaller ship for the next decade. All of the smaller nations or anyone who wants to go to smaller stations could use the Falcon insted of waiting for a seat on the big rocket.

I foresee an opportunity to accelerate the man-rating of Starship by ferrying crew to and from it via Dragon capsules, rather than launching or landing with crew aboard, but no escape system. This also has implications for the continued use of the proven Falcon 9.
