I'm trying to think of possible reasons anyone would want that but I can't come up with any.
Maybe someone is preparing for the first available quantum computer to crack them all

What are we going to gain from you doing all this? I can't find any reasons maybe you can share.
Then why are you posting on the Dev board?
Are you sure you told LoyceV about this?
Yes. What's with the shitposting in this thread?
OP asked me to host the 40 GB file.
Though public keys are not private but don't you think putting them all in one easily downloadable database will make tracking and clustering much easier for analysis companies?
Oh noes, someone shares data from the blockchain! Those blockchain analysis companies would never have thought of that on their own!
/sarcasm





As for questioning why: it's data, and I like data:
Whoever wants it, can have it. If anything, you can use it to prove to yourself how secure Bitcoin is. Did you know that every time your wallet creates a new Bitcoin address, it's basically
brute-forcing all existing addresses, even if it's just one address at a time?
Everyone who ever installed a wallet has attempted to brute-force a funded Bitcoin address
and failed.
