The law was actually far more intrusive back then than it is today. For example, you might be shocked to discover that Jim Crow laws actually mandated discrimination in sexual relationships!
The closest we've come to trying this kind of thing is the present day, where at least sexual relationships have been deregulated. (This one is a biggie for me, I discriminate pretty strongly against white women and think the government should not restrict my freedom in that way.)
Here's one of their maps: https://en.wikipedia.org/wiki/Redlining#/media/File:Home_Own...
Separating whites from colored was also explicit government policy. It was called Jim Crow. We never tried "this kind of thing".
