As long as human beings still have the greedy and selfish nature, there will be people who continue to build mines and nodes for Bitcoin to get profile. These actions convert the energy in human nature into electricity and then into hash rate to support the continuous development of Bitcoin.
It isn't just all about greed when people keep on building mining farms for bitcoin. Well, they got the capital and they sure will have to get profit but it's also helpful to maintain its network.
You are thinking the negative side for someone who doesn't mine but I think for the perspective of miners, there will always be the good side of it.
