He's a rightwing crybaby and also a fool. But that tax is a problem.

For example, it's not restricted to tradable assets. Some assets are exempt, but ability to trade is not a reason for exemption. If you own an asset that's valued at x, that's it, no matter whether you can sell a part of the asset or not. If five friends set up a startup and then they get a first round of investment, those five friends are going to have a tax bill based on the investment round, and the inability to sell shares in an unlisted startup isn't relevant.

I pay my taxes with my head held high, but I also do object to being required to do something that's practically impossible.
