There is no streaming service on this planet that's a "home" for anything. We've seen that even if the company behind the streaming service owns the media on it, they can just take it away for tax reasons or to avoid paying residuals (Disney+, Max), and everything else is licensed temporarily and all it takes is for the streamer to decide they don't want to renew that license and then it's Gone. Yes, even movies you "bought" from iTunes, Amazon, or any other digital storefront. There was drama just a few months ago over Sony announcing they'd delete purchased Discovery content from users' libraries, and I found it both bizarre and irritating that nobody seemed to address that that the reason was not just laziness or malice on Sony's part - but a business decision to not renew an expensive licensing contract. Which they changed course on for now because the press was so bad, but then people pretended like the issue was Over and Resolved, but it isn't - I guarantee next time that contract is up, they will just not renew it without announcing it.
You want to see The Butterfly Effect again? It's not on any streaming service? A quick Google reveals the Blu-ray is (in USD) $15 on Amazon, a double-feature Blu-ray of it and the sequel on eBay for $12, and if you don't care about HD, the DVD is like $6. It's not a hard movie to find. If you can afford multiple streaming services, you can afford a small collection of your favorite titles on disc, and it's a good investment if you like your favorite media not magically disappearing overnight.
