I think if states become more heterogenous (and SCOTUS seems to be on that wavelength) the idea is "if you don't like the new laws, relocate". Which sounds great; more diversity of laws, more states that are likely to fit my values more closely.
But this impacts poor people disproportionately. If you're poor it'll be hard or impossible to relocate.
It also impacts people who consider themselves something other than "rootless cosmopolitans".
I do happen to proudly put myself in the rootless cosmopolitan category, but I've had some interesting interactions (even here on HN) with people for whom community, place, family ties, family history etc. are much more important than they are to someone like me. "Relocate" is a particularly jarring edict for such folk.
