It's still wrong a wrong comparison. Bitcoin network's energy is expended for securing the block. It means that to revert a 1 hour-old transaction, an attacker would have to consume double the energy the whole bitcoin network expended in that hour. More energy expended == more security. Number of TX is totally irrelevant.
