You could have the whole thing made in a factory which just weaves steel cable onto the ends of rods, and then pack the whole thing in a truck and on site just attach a winch to tighten the cables and your building self assembles itself.
I believe many (most?) of these structures tend to have single points of failure, and you don't want your whole building collapsing because a single line broke.
But it need not right? You could easily weave 6 strands in different paths through all the rods and do calculations to be sure that any two could fail and the building still stand.
Sure you now need to tighten 6 cables with a winch rather than 1 to assemble your building, but it still seems like it would be far quicker than traditional frame construction.
Traditional frame construction is a highly optimized system. A skilled framing crew can put up a house in a day. And I'm talking a crew of 3 or 4 people. It's pretty hard to beat.
