“Yeah, sort of like your stocks and bonds and your debit card.”
All of those except maybe the debit card existed in a pre-internet world and were managed just fine. Credit cards have been around for many years. Those systems could return to be implemented in their original form. Balances can be kept track of in paper form or a local computer. Not so with bit coin. Even now they do not gobble up mass amounts of power to access. Simply shut down the internet or access to it and there no longer is any bit coin.
Baloney. Nobody holds physical bonds today. Do you have stock certificates for your investments? Nope. Your bank account ledger will not give you a dime when power is out and banks are closed. Think anyone will take a check when the banks have no power? And btw… Bitcoin springs immediately back to life when power comes back on. And I have yet to hear someone realistically explain how power goes off everywhere… or forever, and not just for a week or two.
