First issue, nowhere has it been stated they are going to or want to totally separate from humanity. Its never been stated by a character, never been shown in a comic. Its been directly refuted by the actions of the mutants and the X-Men. In fact, you have greater engagement with the humans after Krakoa than you did before.
Second issue, the question about human ties, once more,
is being addressed. Its a running plot in Excalibur and its reasonable to assume it to be one of the central plot points of the upcoming X-Men FF book. Comics don't have to answer every plot point in issue #1. The answer may suck and may be deserving of criticism, we won't know until its actually given.
Third issue, If someone doesn't want to go to Krakoa why would that be an issue? What reason do we have to even assume its an issue?

Correction, Usually, that's
one step in a few considerations
of many. There are a lot of things they have to address and most of what they are looking at are still about creating a new state, not even the major considerations of running it. Whats more considering the long running, extinction-plot-of-the-week status quo the X-Men had been operating under before Krakoa. The logical first steps would be
1) Creating a safe space
2) Getting people from unsafe places to the safe place and
3) Protecting that safe space...
Hmmmm...Coincidentally, that looks like a summary of the core plots of X-Men, Marauders and X-Force.
