I don't think we know whether the communication advantages of putting lots of hashing power physically close together will outweigh the extra cooling costs of doing that (or maybe some other tradeoff I haven't thought of). That would be a fine topic for another paper....

Yes, but the block maker won't publish the second block it finds for the same set of transactions. It won't orphan its own block. In fact even if it does it still doesn't matter because the block maker still gets the block reward irrespective of which of the two solutions are published.

It's not about which hash wins, the issue is who gets paid as a result.
