While I was still on Windows, the killer feature that kept WinRar installed, instead of only using 7zip, was the simple fact that its file explorer supported hotkeys like Ctrl+C, and that you could seamlessly copy files to and from Windows’ file explorer.
This might be philosophical, but I think a lot of people make a mistake, when they assume that just because something is made up, it somehow makes that thing less real, and less of an obstacle to overcome. The quality of being made up says something about a thing’s origin, not about its level of realness.
As stated, that notion might be philosophical, but following it’s own rules, that doesn’t impact the degree to which it, as with any other idea, exists as a thing that has the quality of realness (distinct from truth value) to it.
