When I was a teenager there always were a few used mags that we swapped or gave each other. If kids have smartphones, they'll resort to video sharing, and there are few ways to avoid it.

Pretty safe until a machine in the network gets infected. The first infection comes from a phishing email or similar. From then on, the worm infects other machines connected to the same network, but usually not across the internet.
It uses a vulnerability in a protocol that's used for network sharing, and that's usually blocked at your router

And Hewson Consultants did the same in their "interactive video adventure" Avalon circa 1984. The game -for the Sinclair Spectrum- asked for a four digit code printed in non-copy blue that came in the box. Quite a few games would do the same later, like Larry's, monkey island or Elvira, Mistress of the dark, with different approaches, but Avalon's was pure blue over white paper.
Now combine Hyperloop with self driven cars that you can take at your convenience in both ends to arrive to your destination and most of the problems you stated seem easy to overcome.
Probably in a few years, when the hyperloops are ready, owning a car won't be as usual as now, but you'll be able to pick a self driven one paying per mile or a fixed per monthly quota.
