Except that a private company trying to conserve capital could be able to launch satellites in any orbit from one site at no additional cost.
Can anybody see moving their launch to Alaska for any other reason than to achieve a high latitude orbit in the first place? The fuel cost to launch would be the same since all that equatorial velocity wouldn't be wasted. It would be an automatic tourism selling point: see the whole world from Alaska, not just that soul-stultifying equatorial band.
