The distinction between value and wealth is functionally meaningless. If they could liquidate the item, then it counts as wealth. It isn't about "stacks of cash" at all; it's about not letting someone take stacks of cash, convert it into property to avoid being taxed on it, and then liquidate as needed when you need cash again.
If you separate the two, you just create a super-exploitable loophole.
We're also engaging in "boo-hoo, the billionaire might only be a hundred-millionaire" type nonsense, here, which really doesn't bear consideration. They're not suffering. Progressive tax brackets on these things prevent that ever becoming the case. They'd just have you believe that a rich person "needs" their 14th Maserati the same way a few thousand working-class people need regular, healthy, quality meals, and thus it's "unfair" to ask the rich person to maybe only get by with a couple Maseratis while those people get to eat proper meals regularly.

All of this is complete horseshit. Literally, bullshit propaganda designed to justify human rights abuses.
Labour demand is a factor of population. That population is what creates demand for products and services, which creates demand for labour to provide such. If you kill the unemployable, you reduce the population by 5% or more. Demand for products and such falls, cutbacks occur, people get fired, there's less jobs available, and now you're back to a similar level of unemployment. It doesn't fix anything. You're going to rely on the very temporary bump in apparent employment numbers before the market readjusts to try and claim otherwise, which is a deliberate lie, one with malicious intent behind it.
If what you're saying made sense, then we'd have unemployment rates up around 65%. Because the labor force in 1950 was around 60 million people, and it's around 160 million today. The number of jobs would have remained steady, if you were right about any of this. Clearly, it didn't, because population creates demand. Directly.
The problem isn't population, or population growth in "wrong" demographics. That's bullshit and it's based on no data and claims that have no basis in fact whatsoever.
