It is an interesting arguement . . . Should they frame their issue as a refusal to pay taxes as a protest toward how the taxes are used, I might be more sympathetic. But in my mind, citing long-discredited legal positions about the illegality of taxation in general seems foolish. And my larger point is: do we (or they) really want a country that lacks the benefits put forth from taxation?
I have no problem with taxation. However, finding the correct balance between public and private investment and achieving an ethical balance between use of public tax funds is a fertile area for debate.
And I guess I'm not very sympathetic because I paid my taxes and am now $X poorer for doing so.
