It certainly won't result in banning the Bible, but it's still useful (theoretically). It's the same idea as the infamous Baphomet statue that was submitted to that courthouse which insisted on displaying the Ten Commandments: It shows how absurd a law (or in this case, a legislative body) is in practice.
I guess you're right that little will come of it, though. This isn't about a silly law having absurd consequences, it's literally just Christian Nationalism taken to its logical and inevitable next step. They know what they're doing is hateful (AND UNCONSTITUTIONAL), but it's okay because they think (erroneously) that their hate is Biblically justified.
They're also astoundingly un-American-Dream, almost like they only ever wielded a fake version of America to serve their bigoted purposes... I hate being so cynical, but it's hard to imagine that these "American" ideals were ever real. I shudder to think about what their faith, their meditations with God, must be like.
Whenever I talked about organized Christianity terrifying me, this is literally what I was afraid of. I was right. All good Christians need to be loudly fighting against this sort of thing or, I'm sorry, be associated with it. (This is true of any group or movement - I'm certainly aware of toxic/hateful leftists and atheists, and I spend a lot of my effort going after *them* instead of fascists and religious people. But we don't have rogue US states setting up guillotines or banning the very mention of religion).
