I think it is a mistake to assume that government corruption and inefficiency can't explain any delay in government action.
Point taken. I do recall from the tv series they do not have bathroom facilities inside their small trailers either - so all those families are using (or most of them) some kind of communal bathroom.
I think its a mistake to assume that laywers backed by left wing pressure groups can’t keep a legal process boiling for decades - especially if they are paid by the hour.
