I agree with part of what you are saying. Shale is still in basic research. We still don't know if this is feasible. Oil sands are definitely feasible IF you have a source of low cost power to run the conversion process.
Producing oil from coal is a well understood, well known process and the United States has the plans that the Germans used for the plants that produced oil from coal in WWII. No one knows for sure what happened to these plants at the end of WWII. Some think that the Americans dismantled them and brought them to the US. The patents exist and the plans used to build the plants in Germany exist.
Neither shale, tar sands, or coal will or can replace oil in anything except the extremely long term. However, in the short term, industrial scale facilities which are ready, willing, and able to produce large quantities of gasoline from tar sands, coal, and oil shale can put a damper on escalating oil prices.
The United States should develop high capacity industrial facilities to produce oil from coal, tar sands, and shale in the areas that contain large quantities of these resources. This capacity would serve as a deterrence to oil companies arbitrarily raising the price of oil. Also, the United States would be in a position to stop buying oil from its enemies.
The US should put together a Manhattan project style project to get industrial facilities for producing gasoline from tar sands, coal, and shale up and running as fast as possible.
