No, because if it's in private, I can't access it. What good is preservation of knowledge and culture if it can't be accessed by anyone but the select few?

i don’t really understand the connection between “publicly accessible” and “preservation of knowledge and culture”. these are usually distinct subjects.

Who is it being preserved for and why? For a select few, as a bragging point? Or for y'know, all of humanity to preserve their heritage?

If knowledge and culture aren't accessible to the vast majority of people, they're not being preserved for humanity. They're locked away from humanity and they might as well be fully gone.

with this comment you're basically dismissing most museums, universities, archives, etc etc

Are museums not publicly accessible? That's their whole point as far as I'm aware.
