Once cash is contaminated with anthrax, the first person to roll up the Dollar bill to later snort coke is going to get inhalation anthrax along with their cocaine high.
But, it didn't happen. And the attacks were nearly ten years ago.
All the money that you believe was so covered with anthrax that it was able to thoroughly contaminate a three story building didn't infect the woman who collected the rent, it didn't infect her husband who presumably took it into the AMI building, it didn't infect anyone who handled the money at the bank, and there was no sudden epidemic of inhalation anthrax among coke sniffers.
Your theory makes no sense. It is totally contrary to all known facts, and it is unsupported by any facts.
