Good point. Although it's not a flawless solution. It's a good solution to the extent you can't practically shift your consumption to a different jurisdiction (or nation) that doesn't tax the sale of the item. Tricky part becomes capturing consumption tax at customs for items purchased elsewhere to dodge taxes. When you think about the large purchases you can make elsewhere and import with relative ease (like an expensive car) versus the things that can't practically be purchased elsewhere (like groceries), a consumption tax can end up looking regressive. I am a fan of a consumption tax that doesn't kick in until you are over a certain level of spending, so if you consume below a taxable minimum you pay nothing. It's hard to imagine how this would be administered in real life.
