It is very strange. You don't need to do any of those things to buy a soft drink from a vending machine so the same should be true for bitcoins. Are they worried about counterfeit bills or something? I can understand why an ATM might demand ID if payment was done via reversible means or if there was the possibility of card fraud but otherwise, they shouldn't ask for ID, hand scan, photo, phone number, etc.

That being said, once you have the bitcoins in your possession, it should be easy to destroy the link between your ID and your BTC by sending them to a mixing service, right? Or just depositing them in an exchange might do the trick.
