That can be weaponized, though. US government publications are public domain. So is the Bible. We’d at least get to watch members of the Texas government tie themselves into knots worthy of a game of Twister as they try to argue that those texts are harmful on a porn site but not anywhere else.
It isn’t in their best interests to threaten the loony Christian sects that are one of the right wing’s favourite brainwashing tools. Members of those sects rely on authority figures to “interpret” the Bible for them instead of actually paying attention to its content, but if you try to take it away from them, they’ll throw a fit like a toddler does when you take away a toy they’ve been ignoring. Restricting access to the Bible in the present day would make religious brainwashing more difficult and create more people who actually think for themselves, which is anathema to bad governments like Texas’.
