So what prominent public figures are aligned with the philosophy of bitcoin? In the realm of modern economics, most of the "great minds" seem focused on central planning: central banks, IMF, World Bank, insolvent banks, etc. It's fun to play God by moving billions or trillions of dollars from one part of the world to another via taxes and public policy. This is the fastest way to change the world, if they can convince enough people to give them the keys.
No offense, I just think that they don't understand bitcoin. The vast majority of people will not understand why they should use bitcoin. Why do you expect the same of economists?
