Bigger chips = more distance to cover for your electrons = more power required = more generated heat = slower throughput for your data.
Surely you don't believe that the entire chip industry had not thought of "wait what if we just make the chips bigger".
AMD hiding Threadripper behind their back: Uh yeah what a terrible idea, we definitely didn't actually do that. Making a CPU that's twice the size, how ridiculous would that be right?!
You found an exception to my two-line generalization. Congrats!
The main reason to reduce feature size since quite some time has been to make more money per wafer, and faster.
Same reason that so much work was put into increasing wafer diameter over the decades.
More chips per wafer means a lot.
Much more than for performance sake.
