Since you seem to be a devout member of the the Church of Bitcoin, with the initial paper as your bible and Satoshi as your prophet...
It might have been implemented by Him, or at least with His implicit approval:
I'm not playing this dishonest game with you. Here are comments from both of those individuals ON THAT SAME PAGE:
Satoshi wrote:Doing your own verifying and indexing is the only way to be sure your index data is secure. If you copy blk0001.dat and blkindex.dat from an untrusted source, there's no way to know if you can trust all the contents in them.
THIS EXACTLY WHAT I HAVE BEEN TRYING TO HAMMER INTO YOUR HEAD, POST AFTER POST.
Jeff Garzik wrote:Who said untrusted? The proposal is that you distribute blk0001.dat (and only blk0001.dat) in the bitcoin.org official client downloads. And of course the client will spend some time verifying blk0001.dat upon first use. This is unavoidable, and nobody has proposed changing or eliminating verification.
Except that's exactly what you are proposing here.
