People who have been actively & openly working to attack bitcoin (explicitly in their own words) want something because it would improve their ability to attack bitcoin. You cannot imporve bitcoin by making it easier to attack. 

People who do not think adversarially should be just totally dismissed when it comes to what that want to do to improve bitcoin. We live in an adversarial world, and in this case you don't even have to guess about whether this one might be used against us or not, it absolutely will be.
