Wow, a lot of not-really-right stuff in there.
The reason for a big screen is for a big image, not merely numbers of people. Sitting closer to a TV does not make it "bigger" it makes it closer. Our brains know the difference. Increasing field of view (by moving closer) does not automatically fool our brains something is bigger. If that were true, we would be continually baffled about the size of objects depending on distance: "Hey that car parked down the street is only the size of a shoe-box. Wait, now that I'm closer it's bigger than I am! I can't figure out how big this thing is! What sorcery is this???!!!"
Our brains have multiple ways of judging the size of an object so it understands the size, close or further away. When I move closer to my computer monitor, my brain doesn't think "Wow, I'm at an IMAX theater"
it just says "I'm closer to the small moniter image."
Right now I'm using a beautiful 5K iMac monitor and at my usual seating distance it actually fills more of my FOV than my projection screen. But it never feels like I'm watching a really big image. When I watch video clips, shows or movies on my computer monitor never do they feel "big" as they do effortlessly on the "actually big" projection screen. That's why people buy projectors.
BTW, I used a plasma for many years and did everything in my power to make the experience more immersive - always watching with the lights out, making the area behind it completely black so the room disappeared, it was on a projecting arm so I 'd bring it out close to me. I was nonetheless craving more immersion and - before I'd considered projection - I extensively demoed the 65" Panasonic plasma, set on getting that. I watched it from quite close in the store demos, and at home I was trying to figure out how to arrange my furniture so I'd be viewing it close and immersive, but without the furniture looking silly with respect to the seating distance. To help me get my viewing distance to the plasma I borrowed a fairly cheap business projector from my pal. I projected a 65" image on the wall to mimic the plasma size, experimented with seating distances for immersion, etc. Then for the heck of it at one point I zoomed the image big on the wall and...whoah!...it blew my mind! I re-arranged the seating back further, for the bigger image, and it was still a completely different experience than sitting closer to the smaller projected image. Or sitting close to my existing plasma. It was effortlessly BIG and the very first time I had a truly cinematic feeling. I played some scenes from Jaws, one of my favorites, and for the first time since I saw it (30 times) in the cinema as a boy, the shark looked BIG again, life-sized, and menacing.
Put on Star Wars, and, again...for the first time since it was in the cinema, it looked cinematic. The spaceships no longer looked like the toy-size I'd grown to expect via watching it on TVs or my plasma - they looked BIG again.
For a movie fan like me, there was no going back after finding out I could have that experience in my own home.
I ended up making a variable image size system with 4 way masking (so the screen changes size and shape to accommodate any movie AR - another benefit of projection), and use a JVC RS600 projector with amazing contrast.
If sitting close to a flat panel were equivalent, then all my friends who own flat panels wouldn't be continually wanting to watch sports and movies at my place.
Many times friends/acquaintances who have watched a movie on the big projection screen have told me later "I was watching a movie on my (flat panel) TV and I couldn't help think how much better it would be watching on your screen!"
Now, all that is NOT to say there's anything wrong about someone preferring a gorgeous OLED to projection. But you can't expect the immersiveness and the sense of commanding sense of size as a big screen, even sitting close. (And sitting THAT close to a TV screen can feel awkward or uncomfortable for some people).
