Fight the political system from within it? No, don't ignore it but do walk away. We are in the middle of doing that for the banking system, right? Banks are the real government too.
There's no hope in changing the system from within it. Then we have the walk away option or the bloody revolution option. I prefer the walking away option for now.
The difference is, the banks don't own a monopoly on violence. They don't break your door down and flashbang your family. Creating alternate systems is what it's all about, but refusing to be involved in the political system is precisely what they want you to do.
