Look at Fannie Mae and Freddie Mac for an example of taking more than a sliver. https://en.wikipedia.org/wiki/Federal_takeover_of_Fannie_Mae...
I'm not sure of the difference between a "wealth tax" and a "property tax". Are you saying the sort of property tax homeowners pay in a lot of places would be unconstitutional at a Federal level? Or are you saying it's unconstitutional at any level?

The federal takeover of a government-created corporation in a financial crisis to prevent it collapsing isn't really a good comparison to an ongoing process of "taking" large chunks of successful companies because their owners are required to pay taxes. And there is criticism of that control now, even if people accepted those actions were required at the time:

And having the US Government "seizing the means of production" - and that's how it would be spun - is a great way to turn people against it!
A wealth tax is most likely unconstitutional anyway, the same way income tax was before the Sixteenth Amendment.
