can someone verify the gnupg Fingerprint for pubkey?

I downloaded the GnuPG program. I then ran --verify and was told that the key was signed with 0x4F25E3B6 key. I download 0x4F25E3B6 key from a key server and then asked people on this mailing list to confirm that I downloaded a legit key. Several people on this mailing list confirmed the fingerprint of this key as a legit key. I then marked the key as trusted because I verified the fingerprint. I then gpg --verify the gnupg program and got a Good Signature. 

Of course it would be good to meet Werner and look at his passport and all this nonsense. But that is ridiculous because it's never going to happen. I read the GnuPG manual and what I did is what the manual describes as good practice. What you describe is just nonsense. Yes, it is truly secure and everything but you know completely impractical, so why did you even write it?

My question was an honest one and made in good faith about trying to learn and be humble that I don't know everything. But I struggle to find what can be learned from your email. I did follow your link to the posted public key. However I had already downloaded from a keyserver the key that was identified as being the one that signed the gnupg program (0x4F25E3B6). And others verified the fingerprint. So do I still need to download the key that you posted a link to, aren't they the same key???? Strangely, before I downloaded key 0x4F25E3B6, I searched the website looking for a public key to download but did not find the link that you provided.
