Why Don't the People that Don't Like Boxers Just Make a Guild That Doesn't Allow Boxers?

I don't think anyone is claiming that it didn't happen back then. The issue is how much easier it is to box on multiple computers with how cheap they have become or run multiple boxes on a single computer due to increases in power. It is much easier to box in modern everquest then it was when it launched.

Exactly right, no one with any sense would say it didn't happen. I had an acquaintance who ran a 6 wizard murder squad that he used to farm stuff like Fungi Tunics to sell on eBay. He made enough that he ended up having tax problems and had to sell off a car and several computers.
