Luke? Luke states to this very day that 0.5Mb is enough. LOL
He has his reasons.
Yeah, he wants to hurt the entire bitcoin ecosystem because he is a narcissistic prick. That's not a fucking good reason. That or he is just an uninformed retard, doesn't really make a difference.
I fully disagree. Luke-jr is a honest small blocker and has been consistent with his view for a long time. Anyhow: 1) He has had very decent contributions to the code. 2) He had written that HF proposal that increases the block size eventually.
Waiting for his very good reason to halve the transaction volume.
Increasing the block size != improving scalability.
Of course it is. More people means more value, and right now we are at about the limit of what the network can support. It's too basic to even talk about here, or at least it should be.
