Why do we think Dyson spheres exist. It's completely conjecture.

Yes. Also, conservation of energy is completely conjecture.

Personally I think it will ultimately prove out to not be true in all cases. I might sound like a heretic for saying this and would be berated in the scientific community for saying that, but in the past most laws that establish constraints eventually prove out to be only true under certain controlled environments.

Conservation of energy is not a separate rule. It's a direct mathematical consequence of laws of the universe not changing as time goes by. Read about Noether theorem.
