You have x shares of stock, each worth $a. Your net worth is $ax.
The government wants p% of your wealth, so it takes p * (ax) dollars from you. I hope we can agree that this is the same as a * (px). In other words, they've taken p% of your shares.
Why does any of this depend on mumbo jumbo about FMV and 409A valuations?
$a is arbitrary. It doesn't matter how you arrived at it. As long as you provide a reasonable assessment to the IRS,
pg's original point (which you objected to) is completely correct: an f% wealth tax is an f% seizure of your shares.
And if you object that you can just lowball that assessment; well yes, and by the way you've just conceded nearly every point made by opponents of the wealth tax.
