My country is in the process of criminalizing the purchase of real estate with cash. Laws have been proposed to that end. Politicians have also proposed restricting the amount of "unexplained" physical cash the population is "allowed" to hold.

This is your future if you don't resist.

You shouldn't have to "prove" anything. What a bunch of nonsense.
