Already got a copy on my NAS, I update it every year or two when I remember to.
But you’ve missed the point, my personal access to a Wikipedia text snapshot is not equivalent to the free access of information to everyone. The information just existing somewhere isn’t enough.
And anyway a person can’t practically keep their own copy of the Internet Archive. It takes up something like a quarter of an exabyte

Yes of course
But every single scrap of information in Wikipedia exists somewhere else
Its value is twofold and exclusively these two when you boil everything down:
There’s very little else we’ve created that hits both of those, but the second is by far the most important.
