In that case you’re actually using a limited resource: space on a train. And by occupying it you’re preventing someone else from using it (assuming a full train). Copying media doesn’t cost any resources (ignoring the tiny amounts of electricity) or interfere with anyone else’s ability to use that resource.
They don’t compare.
Your post is lacking information. What do you WANT?
Do you really care about the quality and want 4k if possible? Are you trying to scale media amount? In that case, 4k remuxes will need an insane amout of disk space compared to 1080p. Do you need to support multiple people streaming, so transcoding and bandwidth is relevant?
Without knowing what you want to achieve it’s impossible to make that choice.
I think they are rather isolated. At least I have a hard time finding cases.
Here is another one, but this guy was running a website for sharing pirated stuff, which I think is much easier to track without violating privacy laws.
Yes. This was the very first conviction in Switzerland for pirating music.
They were fined 1000 Franks + the court costs (so basically slap on the wrist).

The guy owning the Xhub.com domain is rubbing his hands right now.
You’re technicall still using the company’s resources (it costs some energy to run the empty train), so I still don’t think it really compares to piracy.
But since they are miniscule compared to what they are wasting by running largley empty trains I think it’s morally ok in that case.
