I wouldn't go to a restaurant that used QR codes twice. But I can't go to a different supermarket as there's only one in a reasonable distance away, or use another train line, or avoid a government form.

Yes. If you create a straw man, you're very convincing. The real world isn't a static snapshot though. If people are unhappy enough with existing businesses, they will find alternatives or new businesses will see opportunities. Or you can move to a place with the type of businesses you prefer.
