A wealth tax. This will not go down smoothly. Existing wealth is much harder for governments to find and extract than income. 100 K euros (in 500€ bills) could be stored in a small cigar box. Gold coins would be even more compact. And other valuble items such as rare stamps, books or paintings would not necessarily be recognized as wealth by the new tax nazis. Meanwhile, other stuff could also be passed off to relatives for safe keeping.
If like that happened in the US, especilly with increased gun sales, you can bet there would be more than a few Wacos.

Maybe. Anything bought with a credit card is traceable, up to a certain point, I dunno how long. A case in point is that I need some of my mastercard records from 4 years ago. They were there and retrievable.

Yes, a wealth tax is probably even more destructive than an income tax, since it leads to hoarding wealth in sterile unproductive stores like gold and currency, rather than investing in things that will grow the economy and feed the bloated Saupreißn lounging in sinecures in the DIW.
