Of course most people wouldn't want to be denied access to their bank accounts or prevented from going into a grocery store and shopping in general. That's why it's gradually being done so that people don't realize what's going on.

Then at a certain point many more downloads could be banned and ultimately, people can be shut out of their digital bank accounts.
