In much the same way that a driver’s license and/or passport and/or service card is a “must” these days.
You didn’t need any of those in the days of the California Gold Rush, so philosophically one can argue we don’t need them now. It was totally free and democratic. Never had it so good.
Want to be a doctor and sell homebrew quack meficine? Just call yourself a doctor, it’s not like anyone will check! Want to drive a stagecoach at top speed through a kids play zone? Just do it; there’s no test.
And so on.
The difference being that this new "digital identity wallet" will be required if you want to enter a shop, board a city bus, or drop a letter in a mailbox.
My initial comment pertained to the weasel-words "can be used" appearing in the excerpt - and that they will undoubtedly morph into "must be used" faster than you can imagine.
Your sarcastic comments about medical licenses and such suggests to me that you are in favor of ever-greater govt. intrusion into our daily lives. Am I right?
