You will need money if resources and the means of production are concentrated in the hands of the few. For example, there's no guarantee that access to housing will be democratised.
It will be open source versus closed source. Automation lends itself to being computer driven and people will be desperate for a way to share in the benefits, so they will rebuild from scratch and open source their own automation tools. It's already happening with the Fab Lab Network[1].
I think it's a bit early to try and solve all future problems. Those poor people who will have no jobs need something to do, right? :)
[I agree that "it's owned by someone" can be a problem more than "there's not enough land". Unfortunately, that's politics so I have no quick solution.]
"there's not enough land" wasn't my original point, it was about control of that land, I'm glad you agree it's a problem.
As for what happens to the poor in future generations, it depends on bringing out the best in those with the power to choose. I don't think the alternative is helpful to entertain at this point. The only question is whether we can mature as a race to share without force, or whether balance will be made using force (government coercion, etc...). It's a question about how much faith we have in the human race to grow up quickly.
