i think what you fail to take into consideration is the fact, that even if the chance of a collision may be relatively high by your standards, the chance that the colliding blocks have data of any significance is very, very low. i.e., the algorithm for figuring out whether a hash collision will be important to you personally belongs to EXPSPACE, which, we all know, is filled with pr0n anyways. cheerio!
