They technically can, but then you'd have those satellites spend a ton of their time over nearly unpopulated areas doing nothing. If you instead launch at about a 60 degrees inclination, you spend all of your time between N60 latitude and S60 latitude where it's a lot more populated. This lets you have more coverage in populated areas with fewer satellites. Additionally, there's no satellite to satellite link capability yet, so for an uplink to work you need a base station in range for the satellite to talk to (you can see these as a "wifi" symbol on the map). It's too expensive to put base stations pretty much anywhere in the artic.
