The reported market value of my HIVE account jumps and drops by huge factors. One day the reported value is nearing $5 K. The next day it is around $3 K. If I have to pay taxes on the reported value of my HIVE, I will be sunk.
Yellin's plan would force people to sell their assets at reduced prices to pay taxes and created a recession that exceeds anything the US has experienced before.
The amount of people and resources it would take just to track all of this would be impossibly huge. And since it is the government they would almost certainly do it incorrectly.
