But it's possible to lose a battle you were never going to win in the first place, and end up in a worse place.

I think that if these types of laws (illinois, california) don't hit a critical mass, we're going to see ID verification become the dominant method of age verification. Most websites will use it, and it'll become global because it's easier to just demand an ID and a photo for every user through some third party provider than to offer looser restrictions for the handful of states that have different demands.

This is especially true since it's now been demonstrated that states (like Texas) can go after out-of-state sites serving people in Texas. Sure, you could scrupulously try to identify which state someone is in and use the appropriate level of verification, but then you might be liable if it turns out it was someone from Texas or Georgia or Britain using a VPN.
