If we are going to supplant oral traditions with a massive disconnected worldwide web (sometimes of lies), and replace learned knowledge with 'googling' as a skill- whats the harm in trying to 1. make technologies that will protect the information, or 2. generate a culture of preservation to protect such information.

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!
