Old school answer: by ensuring that such system has a global parliament with global MPs that are accountable to their constituencies, and those consistencies are not immense (this means having lots of MPs, maybe tens of thousands even).
More innovative answer: by developing participatory tools for citizens to engage in the System on a regular basis (such as petitions, referendums, participatory budgets, etc)
