You don’t have to imagine; it has been done many times now against dissidents in the USA through the never before crossed lines of “debanking” in the partial digital currency American economy, the tyrannical cases of the EU sanctioning and effectively turning Jacques Baud and Hüseyin Doğru into 1984 style unpersons, the even more abusive and seemingly tyrants’ template in the targeting of Martin Sellner, where the EU has been targeting him personally across even non-member states in the most tyrannical way. And there are several other smaller, less prominent cases.

As you described, one click cut off from commercial transactions and in the cases of the EU sanctioning its own citizens where even helping them feed themselves or their children is an illegal act.

And most people are totally oblivious to most of these massive shifts in the fundamental assumptions of democratic society, and may even support the tyranny they presumably must believe will never be turned on them, even though no one knows more what a loathsome person a traitor is than those who the traitor has served in his betrayal.
