They won't be doing any of those things under the faritax either! Texas has the 12th largest economy on the planet and no income tax! NONE of that is happening here!
If you would just take the time and effort to actually READ some of the information I have linked to perhaps you might understand! This country did quite well for a very long time without either an income tax OR an IRS!
Bigun, I'm aware of that. Our income tax is very low, by comparison to other states with one.
And while the country did very well without an income tax, it collected excise taxes and tariffs, which while they might not have called it the "IRS" were administered and collected and enforced by treasury agents. They won't go away, because they will be around to collect and enforce any Federal tax.
If there is a prebate, it will take an army to just keep track of the thirty million or more people who move each year and make sure their prebate goes to the right place.
Then you will have to enforce taxes at every point of sale in the US, and the only way to do that is to eliminate cash sales. Every sale of goods or services will have to be tracked to enforce the tax.
Otherwise, there will be a rollicking trade in damaged goods and spoilage and goods destroyed in shipping, out the back door, cash money, no tax.
Oh, there will be an IRS, and it will be even more invasive than ever.
