Read that sentence like "As long as proof of stake exists, proof of work is a 'moot point' toward the environment."

They're making an analogy to the OP comment to argue that it's a bad excuse.

It is very difficult to convey sarcasm through text. If you thought my previous comment was devoid of all reason and thought, may I direct you to its parent?

Please edit said comment to add a /s or similar, its intent wasn't apparent to me either.
