I would argue the reason is so people can make arguments like yours.
Step 1: get easily passed, simple looking laws passed to 'protect the children'
Step 2: 'oh look at all these people bypassing the law. It's so simple for a child to watch porn with this.'
Step 3: increase the requirements bit by bit on the verification
By letting something simple pass, they can claim it's not thst bad, and anyone who argues against it is being hyperbolic.
