Well, having a smartphone is still optional in most countries, I suppose in Germany as well.

Movement on the other hand is a mandatory thing for many people unless you want to sit at home all day...

We don‘t need to wave the ticket at a card reader to use the bus. We just board and mayyybe, like just once a month, there‘s someone on the bus checking the validity of tickets and fining people if they don‘t have one.

What‘s your point exactly? Your concerns seem to be of very theoretical nature tbh.
