Because, as someone else on the Internet put it so eloquently, information wants to be wrong. Sure, you can build your technologies and make your culture and it'll even work for a while, but the average person doesn't really care about all that infrastructure and the rules for preserving content. It's (one of the reasons) why search engines are pushing LLMs so hard - few actually want to search for stuff, they just want to put words in a box and get an answer. They don't even necessarily care if the answer is (very) truthful, just if it's useful!
