  1. Transistor are tiny on off switches. If you put voltage on the gate it turns on the source to drain line. Imagine you have a redstone line with a cut off device in between. When you put a redstone signal to the side of the device it cuts off the redstone line. I believe this is how locking relay works. If you put a redstone relay in between a redstone line then put a strong signal to the side it locks the relay and cut the redstone line.

  2. Making complex 3d structure transistor requires several steps. This steps involves multiple passes to your expensive lithography equipment. That means each wafer will have to amortize a larger fraction of the equipments capital and maintenance cost.

  3. There is no after lithography. The situation is complex but it is not the apocalypse. Yes there is no lithography roadmap after High NA EUV. But there are plenty in the transistor architecture. There is forksheet, CFET, Vertical FET, 2d material channel and many more. This transistor technology together with multi patterned EUV will allow performance improvement for the next decade. The main problem is the escalating cost.
