The Shaw thing was clearly asked to be handled in house. Empath on the other hand I would agree could use more help making a new law isn't going to help his mental state which is the real issue.
The problem is there are certain mutants who's powers are tied to praying on other mutants. Heck Krakoa its self needs to feed on other mutants. So the whole "harm no mutant" law just isn't really taking into account all of mutant kind and their different powers. Respect this land imo does what you are asking. If you are going around like a mad person killing or harming everyone then you can be dealt with accordingly but again that isn't the norm.
Then they wouldn't be on Krakoa in the first place. The council isn't going to suddenly banish mutants who haven't broken the laws just because some citizens are uncomfortable being around them when the island itself is so big.Your 2 examples are not of mutants being outspoken on why they think Krakoa is wrong. One guy who did not talk bad about it and just prefers Otherworld and Brand who is...well....Brand. She puts the solar system above all and would happily take out Krakoa itself if she had to. Realistically there would be those who would be against it who are not anti-mutant humans like Orchis or FoH or the like...just people who have their own, non-malicious reasons for being against it.
Especially when the majority of the council are former villains themselves.
They have already faced multiple invasions from different factions since Krakoa has been started. I just don't think these villains that haven't broken the three laws yet are at the top of their list of concerns.
