The entire DNS database is updated regularly on every web server at every ISP, so there is not threat to its being destroyed. Thats why they are called name servers. When you request a page from a site, your ISP's webserver looks up the DNS and its corresponding IP address, then queries the network for the data from that IP address. The routers take that query and send it to the next closer router, etc. The system does not query network solutions' registry every time.

Use tax dollars to pay for the wholesale ripoff of millions of people's copyright rights? I don't think so. It will have to be a pay as you go system, with micropayments for each use of copyrighted material.

As long as storage media technologies continue to expand, and the speed of the processors processing the search index requests continue to grow, there will be no problem with overload and overflow. Developing filters for properly analysing lare amounts of data is a growth industry and shows no sign of abating.

Most information on tapes is raw data, lists of names, numbers, etc. Magnetic tapes, stored properly, do not crumble or otherwise degrade easily. I am still using 9 track magnetic tapes that are older than I am on a regular basis for list processing operations.

On the contrary, several dozen high altitude, high flux nukes would EMP out much of our accumulated knowledge, which is why most government repositories are now built underground.
