Ok, you must be trolling because concrete and brick have TERRIBLE thermal resistance. The same acoustic materials used in a wood wall give it like 20x the insulation.
And if you are not trolling, you should learn more about a subject before speaking on it next time. The claims you are making aren’t true
They’re not wrong though. You might be thinking thermal resistance as in “can hold a blowtorch to it” in which case sure, bricks might win, but that’s not the context here.
R-value measures how quickly heat transfers from one side of an object to the other, a higher number means it insulates better, or resists thermal transfer.
A 4" brick has an R value under one. It’s like 0.8 or so. 1" thick plywood is already better at 1.25 or so. I think the OSB used as sheathing on the outside of wood frame houses is higher still but could be wrong there. Bricks objectively have worse numbers here
Wood and plasterboard is still a poor insulator compared to actual insulation materials (they’re around 0.035-0.038, with exception of PIR), but still much better than both brick and solid concrete.
Yes. It would cost a few times more. And it will stand for x100 times longer. And it has good thermal insulation. And a bullet insulation too :)

That is the most stupid thought I heard on Internet for the whole week.

No bricks and concrete have high thermal mass, but they have fairly high lamda values making them very poor insulators
Bricks: 0.84
Concrete (dense): 1.4
Hardwood timber: ~0.15
Woodfibre board: 0.11
Plasterboard: 0.16

Would you mind checking the R value of brick for me? And while you’re at it, check what an insulated wood wall’s is?
Brick and concrete have high thermal MASS, not resistance.
Again, please learn more about a subject before you speak so confidently on it. You could have looked it up real quick before posting
Bricks do have terrible thermal insulation. You are probably confusing thermal mass for thermal insulation.
