The danger is when solutions that are convenient, but require giving up some sort of freedom, are made mandatory even for those who would like to stay free. I hope this is a lesson we avoid having to learn the hard way.
I have done some backpacking these past two years, and it is worrying how easy it is to get into big trouble if you lose your phone or payment cards.
As an example, my debit card got eaten by an ATM on my way to Argentina, and after my 6 month travel, the backup credit card I had brought was about to expire.
Despite my card working as a means of payment, I was starting to feel the effects of this corner case in every aspect of modern life. I could not use our equivalent of cashapp, I assume because my card was about to expire. I could not ride public transit, or trains, or do things like book a yoga class with my friends, all because all these institutions basically only let you interact with their service through their apps, where I had no way to pay.
I spent some time visiting friends in the capitol on my way home, and tried to sort the situation out with my bank. They thankfully were able to order some new cards to their office, rather than to my home address. But immediately after my talk with them I found that my one remaining card had been cancelled.
Then I tried bringing my passport to withdraw some cash, but the bank teller almost laughed at me, before explaining that you can't just do that anymore. The bank isn't even allowed to let you get your money in cash and leave. You can get bits of it in bills at the ATM for a fee the price of a coffee, but also that requires a card, of course.
Electronic payment solutions are so convenient, for the public and for institutions, for law enforcement and control, that we've forgotten how much we need to give up in order to use them, and now they're being made mandatory as we trudge along into a cashless society.
Now I couldn't even get food or shelter, if not for my friends. I remember half stumbling out of the bank with my passport in my hand, half dizzy with shock and anger. This, along with lots of other small mishaps like losing my phone and encountering trouble, kind of radicalized me on these topics.
