The peer-reviewed paper to which I linked, which I am not proposing as a replacement for Bitcoin, explains (to those who are willing to read it) why the block being chosen before or after the leader election does not matter when it comes to the security and consensus properties of Bitcoin. It is important for you to understand that this does not matter so you can understand why when the block is chosen does not change the fact that leader election is being performed.

Again, I'll ask you, since you keep dodging the question: if the node elected as leader is (according to you) not choosing the block, who is choosing the block? Why are you so obsessed with whether the value was chosen "before" or "after" the election, which is an irrelevant detail of the protocol? If you can't answer these things and won't read the paper, I don't really see any reason to keep talking to you, because all you've done is make the same irrelevant point over and over.
