I am ignorant about many things but I don’t write articles to prove it.  This delusional idea is so far-fetched it is difficult to image someone thinking it is feasible.
Yes, no stations are complete but there are currently 10 stations under construction and 12 stations will be finished by the time the guideway is completed to Middle Street.  According to your plan, the cost to build these 12 stations would be wasted.
Have you ever seen the top surface of the guideway?  It is covered with rail and concrete pedestals to support the rail.  It would be necessary to remove all the rail and pedestals for 16 miles of guideway before pedestrians or bikes could travel on the guideway.  This would cost tens of millions of dollars.
According to your plan the 43-acre, $700+ Million Maintenance & Storage Facility & the 80 rail cars being manufactured would be wasted.  It would cost 100's of millions to cancel the existing contracts with contractors, manufacturers, designers & project managers.
