Most Americans don't know what laws they would even change, but they do know they need to change. So where to start if that is the only option for now?
Change two laws. The act that authorized the federal reserve illegally should be repealed. Change Amendment 16 to stop the illegal search and seizure of income (taxes), and require all taxation to be voluntary.
These two laws would guarantee every individual is free to use the product of their own labor without violent forced coercion, then you will no longer be forced into paying banks and the federal government to do things they should not do, or you don't want them doing.
Of course it seems unlikely but could start the conversation to a voluntary society. 
I have quite an answer to this. I need time to write it.
