Marxism - and socialism, communism, fascism and other authoritarian forms of control - are all based on coercion and force, the opposite of liberty and freedom.  Bitcoin requires no compulsion or coercion, everything from mining to running a node to partaking in any transaction is completely voluntary.

Marxism's/socialism's/communism's/ etc ideas are so good that everyone has to be forced to do them. 

The capitalists are not the ones wanting to tax and control.  Around the world it is the socialists, communists and fascists who don't trust people to make their own decisions and want them controlled. 

Capitalist systems are dependent on voluntary cooperation and voluntary trade.  All without any centralized coordination, just free people in free markets taking care of themselves.
