Who does all the really shit and boring jobs. Say mining or construction. And can they just take vacation in middle of project and let it hang for a few years? It is really distorted universe where either you have automation or do not... And timeline as whole really does not work...
I guess for projects people consider themselves important this could be done via personal honor system or even just interpersonal relation - I promised my friend the launch loop will be done by equinox & he would sad if I don't hold my word.
