“the underlying reason why we do human spaceflight is the extension of human civilization beyond Earth“
This is a great reason and one that this site agrees with.
Adjoining that should be:

2. the industrialization/creation of infrastructure in space (the solar system).
3. Infrastructure that allows the use and leveraging of the material and energy resources
