 To be clear, we do have techniques to value people's assets. And we have to do so already for inheritance taxes and estate taxes across the world. Now, it's quite cumbersome because there are certain asset classes that are very difficult to value. So it's easy to put a value on cash in the bank or publicly traded shares. But it's much more difficult to come up with a market value for private shares in non-listed companies, residential property, commercial property, agricultural property, art, jewelry.
