This is why I use markdown. I figure that will be easily viewable for as long as the files are around.
I used to take my normal notes as plain text or markdown in a similar structure, so "moving" to Obsidian was just opening the directory. It doesn't show plain text by default, so you'll have to rename them to .md files, but other than that, you're up and running immediately. It's saved the exact same way on mobile as well.
It's the most extensive note management software I've used that also doesn't remove the basics like letting me control the files myself.
Paper on the other hand they at least will pick it up to throw away, likely flipping through it just to look for anything of monetary value.
