An idea to play with:

Currently most states let you put your savings into Bitcoin. Michael Saylor and Larry Fink say it is a great store of value. As a hedge against inflation. When even Fink says it, you think "WAGMI". You buy with KYC of course.

Over time, all your wealth is stored on a public ledger, for anybody to see, no way of hiding what you have. Non KYC BTC becomes illegal, because - terrorists, you know.

Then suddenly, a new property tax law is introduced on BTC holdings, just like we have property tax on land. X percent per year because the wellfare states need to pay their debt, or finance a war.

What are you going to do?
