The issue with such taxes is that they treat stuff like liquid assests which are subject to rapid change, like stocks, as the same as physical cash.
It also brings along the idea that the goverment taxes you when you: make the money, use the money, or even just keep the money. It's just another way to get more moeny even if it's not doing anything.
And with all taxes, it starts only effecting the top, but then they need more money and soon everyone but the poorest of the poor is paying more every month.
If you raise the price of labor through minimum wage, you fix poverty. Opposed to literally everything else plus evidence.
