I have no idea what 'should the people serve the nation' means. Sounds like you wrote something that sounded cool but completely forgot that phrases should actually mean something.

In a representative democracy, the people elect others to represent them in the legislature (and sometimes if it is separate, the executive). There are different ideas as to how representatives should operate/vote. But you would hope that for issues that are too complex for the public at large, the representatives would make the decisions as they are in a better position to do so. Government being accountable to the people has proven to be the best form of governance, but governance by the people has never and will never end well.

At other times on HN we've had the "would you commit a change that you knew would be unsafe, illegal, or even get people killed" discussion. Such as the VW "defeat device". Brexit is another one of those - the worst-case scenarios are extremely bad, and rather than addressing them seriously they get dismissed by the government and Brexiteers.
