Regarding your 1): I often hear that argument, but think of it as too simplistic. I don't need a mask in public, neither do i hide behind walls in the shadows, or wearing a hoodie.

Imagine you are walking somewhere downtown, visit some stores, eating out somewhere, whatever...

Would you like to be followed by a few dozen people, making notices about every move of yours, what you bought when and where, how (much) you paid, while phoning back to some (central) bank to ask how much of your whole balance/credit that was? And always taking photos. And even intrusively interrupting you by standing in your way, trying to push some thing or service you don't even want?

I'd call that harassment, or even fraud, because in case of offered services you don't have time to reason about the obligatory small print.

To your 2) What you are calling engines of wealth, others may call (mostly) a pile of trash, be it physical or virtual. That is not sustainable in the long term, because Ponzi scheme.

3) As others have already mentioned: Cheap move of yours. Think of the children!1!!
