They don't want to make it hard to use your credit report. The worse job they do with security theater the more money they make, and the easier it is for you to obtain credit products. If they actually applied any reasonable security, the friction of getting new credit would reduce new customer acquisition.

For my view, that's ideal: people should put real, explicit thought into obtaining new credit or debt products. It's too easy right now, especially with products like Credit Karma trivializing getting new credit cards.
