ELI5: Why can't they make CPUs bigger if heat dissipation is a problem?

If heat is distributed through larger area/volume it will be easier to dissipate, no?

It's a bit unintuitive, but that's not exactly how it ends up working.

A more densely packed, smaller CPU design made out of smaller individual transistors is actually more power efficient. It suffers less electrical losses, and so it generates less heat. The performance and efficiency benefits to going smaller generally far outweigh any consequent heat dissipation issues that might be caused by the increased density. Removing heat from the die isn't that big a problem anyway.
