I expect that access to inexpensive energy is more important than the population density, typical ambient or "favorable" state laws (this law doesn't seem to really do all that much).

Like the region I live in is cold and has lots of water, but we import energy, might as well build closer to the regional mega cities (where it is still relatively cold, with relatively abundant water). There is some kerfuffle going on in the county here about preventing data centers, and I can't imagine there is even anyone interested in building one.
