I would like someone to explain to me how the government would function without the IRS. Does this entail an end to taxes, and if so, how could the government function on even the smallest scale? If not, how would the government collect taxes?
The general idea (I think) behind most of this type of thing is to have a tax system so simple it's very very hard to "game" and thus you need FAR less bureaucracy to deal with it.
Also, remember that the idea of Income Tax in general is a 20th-century-normal thing. Most "western" nations IIRC didn't have it prior to WWI. I know in Canada at least it was supposed to be a "temporary wartime measure" and then back to normal. But no, once they get your money, they are
loathe to give it back. Prior to that Governments generally worked on taxes on imports (exports perhaps too) and a number of other types of taxes. You need very good paperwork to make income taxes more than a farce (well, more than they already are) so that you can reliably track what people are paid, and thus banks are a massive help there.
And the more general idea here is that the less money the government has, the less it can fuck up (and/or patronage/graft/etc, take your pick). You can only fuck up so much when you don't have much money. The more they have, the more they can fuck up. The opposite view is that the more they have the more they can
help people who need it. Take your pick.
