No one has ever had a fully reusable orbital rocket.. still to this day. Althought starships got a shot.
In general, if rocket building costs could really be reduced to almost nothing, reusable rockets would be useless. The only case where reusable rockets have a chance is if building rockets is still very expensive.
That's what blue orgin is doing with the blue ring concept. Take avionics, data telemetry, battery's, and solar panels out of the design and let the customer focus on what end goal they are trying to achieve. I think blue ring is a very good business innovation as well.
