It seems to be any organization, or even agreed lack of organization could fall under this.

That said, a flat tax would possibly be okay (if not more intrusive), but what would really work is to abolish the income tax and replace it with a national sales tax.

Is there any example of a country that has done this? I personally lean towards a progressive income tax, and that is it. No write-offs, no tax breaks. Just a tax on all income that begins at 0% at the poverty-line, and climbs at the rate of a single order exponential.

Government is there because we put it there. However, complexity can lead to autonomous government power through obfuscation. I think libertarian-minded folk would probably find real advances if they attacked government complexity in lieu of government reach. I say this, because ultimately, I think that which makes our government not our own, is primarily rooted in bureaucracy.

Personally, I feel we should go back to a volunteer government and no income tax.

The US started the income tax in 1812. What would suggest that the first 36 years of US history can be effectively and advantageously applied now? Are there any modern examples?

I do think that a limited number of terms in the House and Senate might reduce corruption, however. Also, I don't think that anyone but a citizen should be able to donate to a campaign, and donations can only be made personally, and directly. Campaign funding is elective power. If our government is to serve the citizens, the citizens must control elective power.
