"Can" will soon transform into "must."
Regards,
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.
