Do not argue with PoS advocates, they abuse the implicit legitimacy credited to them, the honor of being invited to a discussion.
I disagree, because on public forums (bitcointalk, reddit, even twitter) you and the PoS advocate are not alone, a lot of newbies are reading the misinformation that the PoS advocate is spreading so their lies have to be challenged.
It's the same with SegWit, even today we are seeing people who are confused about how SegWit transactions work if they "remove" the signature just because in 2017 someone gave them wrong information about signatures being removed.
