Are you confused? Are you suggesting to reduce miners while increasing miners to maintain decentralization?
So you are admitting that:
1. More miners, the betters.
2. Energy consumption is not harmful, nor bad. It only needs to be “taken into account”, acknowledged if you will.
3. Having a restrict number of actors in a network, such as the Ethereum network, is harmful because there is too much control in the hands of a small circle of powerful people.
