It doesn't work that way. You would have to block a person's access to the internet. If that happened the person could simply have a trusted friend/family member sit at the terminal for them. It can accurately be viewed as a currency you hold in your mind. Those with weak minds will lose that shit through various ways. Those who have sound creative minds will not only keep their assets but they will grow them precipitously. Not only against the dollar but against all other assets as well. Those who have no crypto at all will be slaves. Forced to sell their time/resources/DNA/privacy/etc. to live. Sad to say but that is where we are going... Hell, we are there NOW. Most folks just haven't realized it.
