They can be worked around well enough that it's not really worth the trouble.
That's not the point. In at least one scenario I outlined, the state government is causing adherents to a religion undue hardship and is grounds enough right there to repeal the law.
not enough people are convinced that it's worth the effort to reverse the policies.
No, if you actually read what I linked you, you'll see that you're wrong.

Very very simply put, the court could not be moved enough to see that it caused undue hardship on anyone for any valid reason. It's not that enough people care because it's made it to several supreme courts. In 1961, a SCOTUS case made a decision. But, according to your reasoning here, the values in 1961 hold true today. We already see that that's not the case.
It's not about who's right or wrong here. It's about why they're right or wrong. Revisiting "why" today would render a completely different outcome.
You've misunderstood me. I'm saying nobody gives a shit to undo it. Regardless of how the laws came into being, not enough people are convinced that it's worth the effort to reverse the policies. They can be worked around well enough that it's not really worth the trouble.
