Sure... and for editing a 12 megapixel photo that number is 384MB (raw or jpeg is irrelevant by the way - it's the megapixels that matter).
As you add layers, you need more memory... but to run into issues at 8GB you'd need a lot of layers. And nobody is saying 8GB is enough for everyone, Apple does sell laptops with 128GB of RAM. They wouldn't do that if nobody needed it.
And photoshop, which has it's origins in the late 1980's, is actually pretty lean. Back in those days it was common to only have one megabyte of RAM and Adobe has kept a lot of the memory management gymnastics they needed to fit within that limit. If you run out of memory it will make smart decisions about what to keep in RAM vs move to swap.

Yeah, not sure if they’ve used PS in the last few years, but lean is not a word I’d use to describe it
You’re entirely leaving out the ~2-4GB of system overhead, 1-2gb just to have PS open and then having headroom left on top.
Oh and by the way, Lightroom eats ~45gb of RAM when importing. Also file sizes are much bigger for any decent camera now. I shoot 45MP and files are huge now
