No offense , but ignoring the energy waste will not make the issue go away,
that is like ignoring that mole that turns into cancer and kills you.
This is probably one of the worst comparison I ever saw in my life, but if you are so big eco warrior that stop driving cars, stop using electricity for anything, and don't use your bank and credit cards because they spend more energy than Bitcoin.
PoS was created to fix it, so this has been an issue ignored for years already.
Proof-of-stake is created only to make owners and whales richer, and it has nothing to do with decentralization, security or saving of energy.
Ethereum and Cardano , the #2 and #4 coins on CMK would disagree with you.
As Cardano is 1.6 million times more energy efficient than the bitcoin PoW network, and it onchain transaction capacity exceeds btc to the point , they don't need an offchain LN network to help with transactions.
My point , is without PoS conversion, Bitcoiners are just ignoring the problems,
and if you are going to stay PoW, then how will bitcoin avoid future bans on mining, and those bans are coming , no matter what you ignore.
