Shogo's in the UK, when he's not in Otherworld being a dragon. And we have one person, when we know the X-men have a history of working with numerous humans and other species when the X-men were a super-hero group. You forgot to mention that non-mutants can't go anywhere in krakoa without a mutant 'minder.'
They've had enough time to get things sorted, from the military to education to democracy and all of this is far from high priorities to th government. Xavier was perfectly ok making a big priority by setting up the Quiet Council, an unelected body which he leads unofficially. Those humans were old ladies, it was hardly a Sentinel fleet.You forget they're only some months old and they have already had terrorist attacks by humans, you don't open your country to tourism when that happens.
They should be moving far faster than what we've seen given that many of the people in the Quiet Council have done this before and Cyclops has, too. It's like they've completely forgotten the knowledge from those experiences.
Instead to set up steps which would allow tourism, like having alliances with other countries they've put in more effort to alienate them.
