Might be a fun social experiment to propose a public gun lending armory. Like a library, you can walk in and check-out an AK-47 for a day or week for free. But just like the library charges for printed pages, you would have to pay for the ammo.

What’s TAN?

(edit)
Regarding the train svc, the carsharing, Netflix, etc, I generally draw a line and say all the private sector stuff can be disregarded apart from life essentials like groceries. So in your list, the train service is a good point because that’s a public service which invokes human rights (equal access to public service). Since you mention Germany, I happen to recall some Germans saying that the train app can access tickets and fares that are otherwise unreachable, perhaps in part because some stations have no kiosk.
