> Does that include taxing employee equity based on how it is valued based on each round of funding?

This already happens, except as a tax on income rather than wealth. Exercising options in a private company that has increased in value will result in a tax bill. And you can't sell shares to pay that bill (usually) because the company is private.

That’s exactly my point. Property tax is a tax on wealth. You are not taxed on options until you exercise them. You also can’t sell part of your house to pay taxes on it. You also aren’t taxed on the increase in your stock portfolio until you sell it.
