Why do i want a copy of something I am only going to watch once?

Delete it when you’re done if you never want to watch it again.

And why should I keep a copy if I can just stream it again from the same or some different site for free in the future?

I thought you just said you wouldn’t want to watch it again?

Obviously there are people who do watch pirate streams. I’m just pointing out how odd it is in the context of this thread, where people are complaining about dependency on outside resources, and how alien it is to my personal approach to this kind of thing.
