Wouldn’t it kill your hard drive quickly if every bit in memory was constantly written there - if it was all virtual memory? I think of it like “stuff in my desk” vs “stuff on top of my desk”, and now nobody mixes up the papers on my desk when I walk away.
That’s what RAM is. Following your analogy, you’ll put stuff occasionally inside the desk when you’re done with it, and keep working what’s on your desk. I see persistent ram as like working inside the desk, which is a bit weird to me. Or a desk that just never gets cleaned up.

That last one is how I see it too. Just never gets cleaned up.
