Progressive consumption tax is ridiculous. It requires your tax rate at the point of sale to be dependent on all your purchases to that point in time. That's just not practical. Or it may require every purchase you make to be recorded for tax-time when you then pay the taxes. Either way it requires the government to know every purchase you make, or at least the price. This is not something anyone should want.
That doesn't mean such a tax is not ridiculous for other reasons, though.
