Because you have to remember that the Khala has been a part of everyday life for billions of protoss. It's their main focal point of religion and everything. Only its use as a form of enslavement from what Amon did was considered a recent phenomenon. The old Khala was something the protoss had millions of years ago (most likely longer) before Amon and his followers even came to Aiur. The new Khala was founded by Khas to end the Aeon of Strife, which was in 500 BC. But even if we're to use the new Khala, it would have been part of Khalai protoss life for the last 3000 years. That means the patterns of the religion and faith are too deeply rooted in Khalai protoss life and thinking to be permanently removed. Artanis was only able to succeed in getting his people to cut their chords in order to get sever the link to Amon. With him gone they're going to want to find a way to pick up where they left off. The Evolution book seemed to imply there were those who didn't want to try adjusting life without the Khala....
