> and while the government might take your last 409a valuation as the means to valuing your net worth, they aren't accepting your shares as payment, only cold hard cash.

There aren't any wealth taxes of this nature on the books in the US, so assuming that they will only take cash and not shares is premature.

But I think you raise a good point that payment in shares is far more tenable, and likely probably, for highly illiquid economic assets.
