Honestly, I'm content to both streaming and physical media. I mainly stream shows that are either on the air at the time (although I'm taking a break from simulcasts this season to focus on my backlog, except for Vinland Saga), I'm either unsure about (either based on public opinion or, in some cases, whether I should get an expensive release (e.g. from Japan or AoA)) or if I want to check out a show that has yet to receive a physical release. On very rare occasions, I would end up resorting to other means if no streaming is available as a last resort (thankfully, that's rare with recent anime, but sadly, a lot more common with tokusatsu), not that I would encourage it anyway. Of course, I would never go near any of the illegal streaming sites.
In most cases, I would blind buy the physical release of a show that lacks streaming to prevent going through other means, but I would also sometimes blind buy physical releases of shows that have streaming availability if either public opinion is positive or if I feel that would be the show I would enjoy (and also, to save the hassle of watching it on either Crunchyroll, HiDive, etc). As for shows I have seen, if I liked a show enough when I streamed it, I would get the physical release of that particular show.
The way I see it, legal streaming has a place in the anime community, whether people like it or not, as it's there for whenever people would like to check out a show legally, but can't get an English friendly physical release (either because one is not available or too much for their budget, or they don't want to risk blind buying a series they might not even like). And if I'm correct, doesn't using legal streaming increase the chance of making a physical release and/or an English dub possible (I'm an original language fan myself, but let's not get into that debate)?
While some of the posts I've seen seemed on-topic, I think this conversation should have a thread of its own, if there isn't one already.
