They are expensive ideas - but not fundamentally impossible.

Of course, the politics, not to mention who's going to pay for it may
well be a show-stopper.

This solution can only be done by using advanced robotics to produce
aluminium of the Moon/Asteroids. Sending it up from Earth would be
prohibitively expensive, even assuming launch costs could be
dramatically reduced.

Actually not.
In context - with relatively modest reductions - say an order of magnitude -
orbiting a few thousand tons is not prohibitively expensive for any
modern industrialised nation.
