Oof, talk about making compliance difficult and expensive if a company has 50 different sets of regulations to comply with to do business in the US.

Do you believe that states are the laboratories of democracy, and have rights, or do you believe that reducing the cost of regulatory compliance is a more important goal?

I take no position on this currently, but it's an important question that deserves a serious answer. Trading off the costs of "state experimentation" and "enforced regulatory conformity" is non-trivial to do.
